I'm trying to find a webtoon where this girl's old high school friend started working at her office and she pretends to be a whole different person because she has traumatic memories from high school. Essentially this girl wrote a love letter to this guy but she found out her friend was dating the guy so she went to get it back because her friendship is way more important than any guy but some other guy (aka the old friend) has it and forces her to be his friend. but the letter is leaked and everyone is an ass to her
I'm looking for a romance Webtoon where this girl has a crush on her guy best friend but he has a girlfriend. And this other guy with blond hair has a crush on this girl and keeps interacting with her and when she starts to show interest her guy best friend gets jealous. The cover has all three of them on it. The girl has a bob haircut
Is it this one because the plot sounds like this one
