The Reason She Left Her Swimsuit Behind

When I woke up and checked my phone, it was already two in the afternoon. I'd slept so deeply that forcing myself back to sleep felt impossible. Yuna, on the other hand, was still wandering through dreamland right beside me.

I quietly opened Sexmuwiki and, sure enough, there was a notification. I went straight to Yuna's document to check what had changed.

The phrase "Han Jihoon's exclusive whore" had been added to the overview. Did that mean she was fine being treated like a whore only for me? And the new entry under preferred play—secret outdoor sex—had appeared. She'd looked terrified when we did it last night, but apparently she'd been far more excited than I'd expected.

She used to be a proud, confident woman who trusted her looks completely, but she was becoming more and more perverted by ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the day. Everything else was just a detailed record of what we'd done at dawn.

After reading the satisfying message about the points, I was done with the app. While I was gently stroking Yuna's hair as she slept, her long eyelashes fluttered.

"Jihoon Oppa…"

"Ah, sorry. Did I wake you?"

"No… When did you wake up, Oppa?"

"Not long ago."

After hearing my answer, Yuna scooted closer and wrapped both arms around me.

"Can we stay like this a little longer?"

"Of course."

We lay there blankly, letting time pass. Maybe thirty minutes later, a loud growl echoed from the bed.

"Ah!"

"Hungry?"

"I guess so… Hehe, this is so embarrassing."

"Want to eat? I can make something simple."

"Really? Sounds good!"

Just as I sat up, wondering what to make, my phone rang. The caller was none other than Iseor noona. After asking Yuna for permission, I answered.

"Hey, Noona."

— Are you working out?

"Ah, no. I'm at home. Why?"

— Then can I come over? It'll take about an hour.

"Ah, you're coming to my place?"

I glanced at Yuna. She smiled lightly and nodded, as if it was fine.

"Uh… Okay. See you later, then."

Click.

"…Yuna, I'm sorry."

"It's okay. I can't exactly tell you not to let her come because of me."

"I'll definitely cook you something delicious next time."

"Promise?"

"Yeah. Promise."

I hooked my pinky finger around hers when she held it out. I felt grateful yet guilty that she was being so considerate. As if she wanted to erase even that complicated feeling, Yuna gave me a bright smile.

"How long until she gets here?"

"About an hour."

"Then I'll just take a quick shower and go. That's fine, right?"

"Yeah. I'm really sorry, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Yuna."

"It's fine, so don't worry about it! I'll go wash up then!"

Even as she left my room after saying that, Park Yuna kept her cheerful expression.

===

Shhhhhh. The sound of water from the bathroom stopped. After finishing her shower, Yuna wiped the moisture from her body with a towel.

"…"

She had to make room before the woman Han Jihoon liked arrived. Of course it wasn't pleasant, but it didn't make her feel gloomy either. Given her current position, this was simply how things had to be. She planned to accept it humbly until she could capture his heart.

'Right.'

As she was leaving the bathroom, she stepped back inside. She'd just remembered the cow-print bikini hanging on the towel rack.

'I should take this home and wash it, right?'

Her hand, reaching for the swimsuit, froze in midair.

'Should I just leave it here?'

The woman's voice from the phone call came back to her. The way she'd spoken to Han Jihoon while subtly sending a warning message. She had clearly been saying, "This man is mine, so don't even dream about it."

Meekly backing down after hearing that felt like losing for no reason.

'Yeah, I'll leave it.'

If the woman came to this house without knowing anything and found this swimsuit, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠that alone would serve as her own reply. A message saying she wasn't going to give up on Han Jihoon either.

'Well, if Oppa sees it first and puts it away, then whatever.'

With the hope that the other woman would be the one to find it rather than Han Jihoon, Park Yuna stepped out of the bathroom. Wrapping herself in the long padded coat hanging on the living room rack, she opened the bedroom door where Han Jihoon was and said,

"Oppa! I'm all washed up, so I'm heading out!"

"Ah, wait a second!"

Han Jihoon jumped out of bed and came all the way to the front door to see her off. His face was still full of guilt. So Yuna deliberately smiled even brighter.

"See you next time!"

"Yeah, get home ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠safe. I'll call you."

"Okay, Oppa!"

She was retreating for now, but one day she would definitely become this man's number one. With that resolve, she returned home.

"Hmhm♪ Hmhmhm♬"

Kang Iseor came out of the bathroom after a light shower. She was getting ready to head to Han Jihoon's place, just like she'd told him over the phone. The reason wasn't much different from usual—she simply wanted to be in the same space as the man who made her happy. However, because of the call they'd had before she showered, one more reason had been added.

— Hey, Noona.

"Are you working out?"

— Ah, no. I'm at home. Why?

"Then can I come over? It'll take about an hour."

— Ah, you're coming to my place?

The conversation itself wasn't anything special, but Kang Iseor had felt a strong sense of dissonance. Normally, when she said she was coming over, he would've been excited and told her to hurry. Today, his reaction had been lukewarm.

'Don't tell me he's with another sex partner?'

She didn't want to be hated by Han Jihoon, so she had no intention of interfering with his sex life or trying to control him. Still, the unpleasant feeling wouldn't go away, so on her way to his place, she wanted to find out why his reaction had been so flat.

'By the way, will I find out today whether the collab is happening?'

Yesterday, through her call with An Chaerin, she'd heard about the collab plan with Nayung, another streamer from the same MCN. It was still just in the planning stage, and since they were supposed to call Nayung today, it could only proceed if she agreed. Kang Iseor usually tried to help An Chaerin, the MCN representative and her close unnie, whenever possible, so she'd already accepted the collab offer.

'If it's decided, they'll contact me on their own, I guess.'

Work was work, but right now she just wanted to see Han Jihoon quickly. After finishing her preparations, she got dressed and headed to his place.

"Noona, come on in!"

Han Jihoon greeted her with a welcoming face as he opened the door. Kang Iseor felt a smile tugging at her lips too, but she forced herself to look nonchalant out of embarrassment and stepped inside.

"What were you doing?"

"When you called, I'd only been up for a little while, so after the call I just stayed in my room."

"Really? Your voice sounded weak, so I figured you must've just woken up."

"That was… Actually, I was with her. The other sex partner. She left after hearing you were coming, so she's not here now."

"Ah…"

Han Jihoon volunteered the information without being asked. It wasn't exactly pleasant to hear, but Kang Iseor made an effort not to show her displeasure. As she'd said before, she was afraid he might come to dislike her if she tried to control him. She was also grateful that he'd honestly told her something she would've never known if he'd stayed quiet.

"Gah!"

So she pulled him into a tight hug, hard enough to startle him. The warmth of his body through his T-shirt and his unique scent. Just breathing it in felt like it would blow away all the disappointment of him being with another woman.

"Huu, haa… You didn't shower after waking up, did you?"

"Yeah. I was in bed the whole time."

After hanging her coat on the rack, she buried herself in Han Jihoon's arms again. She pushed forward like that until they reached the bedroom, then shoved him onto the bed, climbed on top, and sniffed him.

"Haaa… This is so good…"

Her body felt like it was floating, and it was as if all the toxins accumulated in her brain were being cleanly washed away. If possible, she wished time would stop right here. But cruelly, an unwelcome signal came from her lower belly.

'Of all times…'

"…I'm going to the bathroom for a second."

"Ah, go ahead."

Leaving her embarrassment behind, she entered the bathroom. She'd already gone before leaving home, so why did she need to pee again? Complaining inwardly, she finished her business and washed her hands. As Kang Iseor turned toward the towel rack to dry her hands, something strange caught her eye.

'…What is this?'

What she saw was a swimsuit hanging next to the towels. A cow-print bikini with an unbelievably small amount of fabric. She picked it up and examined it closely, her already wide eyes growing even larger.

'This is way more revealing than the one I wore!'

There was no need to doubt it—this was definitely not something meant for actual swimming. Anyone could tell it was designed to sexually seduce a man.

'Come to think of it, when Jihoon was on the phone with that woman, I think I mentioned the bikini.'

Knowing that she'd worn a bikini for Han Jihoon, had the other woman prepared an even more provocative one? If so, it meant she saw Han Jihoon as more than just a casual partner—she saw him as a serious romantic interest. Plus, according to Han Jihoon, that woman had also known Kang Iseor was coming to his place. And yet she'd deliberately left the swimsuit out like this.

'…Does that mean she's openly going after Jihoon too?'

A sudden wave of anxiety hit her. Until now, she hadn't been particularly curious about Han Jihoon's new partner. But the moment she recognized the other woman as a rival rather than just a partner, she started caring about what kind of person she was up against.

'Ha, should I try it on?'

With a tense expression, she adjusted the bikini top. The upper straps went around her neck like a necklace, and the horizontal straps tied behind her back. Without needing to get naked, she tried the bikini top on over the hoodie she was wearing and couldn't help but be shocked.

'…How is it this big?!'
