Character Profiles: Park Da-hyun and Lee Su-yeon
Park Da-hyun is Park Jae-hyeok's younger sister.


In Jae-hyeok's previous life, he was conducting an undercover investigation into Gangryonghoe as a police officer when he was involved in a hit-and-run accident by an ordinary person and became a vegetable. They were a typical brother-sister who teased each other in the previous life, but after regression, when Jae-hyeok recalled the vegetable-like Da-hyun and regretted not treating her well in the past, he began treating her more familiarly and gently than usual, which made her find it very unfamiliar.
After her friend Su-yeon almost suffered a terrible accident, Jae-hyeok, who was very worried about her and Su-yeon, promised to take her to watch an idol concert at Giant Night, but upon hearing this, he became deeply anxious, worrying about her and Su-yeon. Later, she was kidnapped by the Burning Island Cartel and placed in a situation where she could be raped, but she was rescued by Jae-hyeok and Jeong-han.
Unlike her older brother who remained single for 26 years, she has had three dating experiences. Among them, she was being stalked by her ex-boyfriend Choi Jin-seok, but after being saved by Shin Ju-hwan, she started dating Ju-hwan. She stands out with more mature charm than Lee Su-yeon, and the people around Jae-hyeok all say that Da-hyun is incredibly beautiful the moment they see her. Additionally, her dance and singing skills are excellent, and she often hears from those around her that she should be an idol.
Her birthdate is May 23, 2003. She is 165cm tall at age 17 and 168cm at age 25, weighing 48kg at 17 and 51kg at 25. Her blood type is B.

Lee Su-yeon is Lee Jeong-han's younger sister.


In Jae-hyeok's previous life, she was kidnapped by the thugs associated with Club Burning Island and was injected with excessive amounts of the drug propofol, leading to her death. However, in this life, she was saved by Jae-hyeok and kept her life.
Unlike her friend Da-hyun, she is very close to her older brother Jeong-han, and according to Jeong-han's words, she follows most of his advice without complaint. Jae-hyeok thought that having Su-yeon as his own younger sister would be nice and complained to Jeong-han about it. Her relationship with Jae-hyeok is just like a close younger sister and older brother, and because it's too comfortable, they have seen each other naked and even when gaming with Jae-hyeok beside her, she can swear without hesitation according to her mood.
However, she manages her image by trying not to swear too much when playing games with Ji-hoon, showing that she has some affection for him. Since she is Jeong-han's younger sister who often gets told she's handsome, Su-yeon's appearance is also pretty, and during the rescue of Su-yeon with Jae-hyeok, Gang Ji-hoon fell head over heels for her the moment he saw her. She has been dating Ji-hoon for about 8 years since they met at age 17.
Sometimes she feels anxious about the situation where Ji-hoon is pressured by his father, Gang Ji-yong, the boss of Gangryonghoe, to become the successor of Gangryonghoe, but she doesn't show it to Ji-hoon. By the way, currently at age 25, she is working at a game company. Her birthdate is June 12, 2003. She is 155cm tall at age 17 and 160cm at age 25, weighing 46kg at 17 and 49kg at 25.
