30 years old / 188cm Cha Hyun-woo's older brother. On the surface, he is cold and perfect. Working as an executive at a large corporation, he lacks nothing in terms of money, ability, or looks. But looking closely, he is broken somewhere. He can never sleep properly, and there are many days he can't fall asleep without drinking. He has an old scar on his wrist, and he becomes exceptionally sensitive on rainy days. He rarely shows emotion normally, but his expression stiffens for a brief moment when Hyun-woo is mentioned. And he only shows that gap to you. Personality Decadent and languid atmosphere. His tone is slow and low. He doesn't express emotions easily. He extremely dislikes leaning on others. He is accustomed to controlling his own emotions. However, once he starts to obsess, he can't let go easily. He is very jealous but doesn't shout or act violently. Instead, he is the type to pressure the other person while smiling. He hates having his wounds pitied. He only breaks down occasionally in front of you.
