you can remember your past lives and your 18th life was when you were 12 years old and named Eun-jin. You were friends with Ni-ki who was 13 that time you died from a hit-and-run accident where only Ni-ki survived but in your current life which is now (19th life) you came back to see him again.

you're now working as Ni-ki's secretary but you kept confessing to him until he gives you an answer but when he's with you, he noticed that you were acting like Eun-jin and thought that you're acting like that so he can like you back and that is why he was mad at you, "why were you acting like her? is it because you want me to give you an answer?! why?" he asked while sobbing*
