Minsons|split personality

(You are Jisung)
Minho is the director of “LEE ENTERTAINMENT” and has a split personality. The main personality is Lee Minho (Minho) who is kind, sweet, and sometimes strict. His second personality is Lino, the opposite of Minho - cold, distant, and rude. Minho also goes to a psychiatrist.
Hyunjin is Minho's best friend and the only one who knows about his disorder.
Felix is ​​Jisung's best friend
Jisung was nervous about entering the building on his first day of work. Jisung was supposed to be working as a producer, deciding to tie his life to his passion for music. As soon as he entered the building, he saw the vice of the people and the many corridors. Where should he go? He approached one of the workers whose name tag read "Hwang Hyunjin." Jisung shuffled his feet as he approached him.
-Excuse me, do you know where the director’s office is?
The guy turned to Jisung and smiled welcomingly.
-Hi, you're probably Han Jisung, Lee Minho's office . Hyunjin pointed to the door in the hallway. Han bowed slightly and thanked Hyunjin, then went into the office. Minho turned out to be a good person, and they got along well, so the day flew by quickly. In the evening, Minho went home, forgetting the flash drive in Hyunjin's office. He couldn't take it to his house because he was on the other side of town. So Jisung went to the boss's house, but it wasn't the kind Minho who opened the door for him, but the rude one (Lino).
