Help me find this movie

Yesterday I found a movie (or maybe it was a drama) about a girl being raped and how she took revenge on them. If you name dramas and movies with this storyline I can look them up and hopefully I'll find it!

I know, that what's bothering me, I wish I could be more specific! :/ I found it yesterday as in read about it while scrolling through movies, I thought I added it to my "plan to watch" list because it sounded interesting. If I remember correctly I think it was korean and quite new. I also have this vague memory that it was a gang rape and that it, at least parts of it, were in school environment. I'm not sure though. So the movie is about her revenge on these boys and what they've done to her. I didn't think much about the details as I thought I had already saved it.

Anyway, I hope that someone have watched this or know what I'm talking about because I really want to see it and it's absolutely hopeless to google it. xD The results are not pretty..

No, it's not the one, it's the girl who avenge herself!

Thank you anyway, I might watch Don't Cry Mommy too : )

Nope, I've seen that one. : ) I'm talking about an Asian movie, most likely Korean and if I remember it right it's set in a school environment! Thank you anyway! xD

No, it's about a girl. Either a teenage girl or young adult. I really want to find it. I've been searching for an hour now with no results. :( Thank you anyway, happy that everyone tries to help!

Omg! After searching through hundreds of movies on MDL and gooddramas, still without no luck in finding the movie, I read through the comments again (and again). And it was Don't Cry Mommy!! xD

I actually found this movie on youtube through a fanmade video and when I saw all the school clips of the daughter and the guy I thought it was the daughter avenging herself, haha! I thought I found this movie through MDL because the same day as I found the video I had been going through as many movies as I could to make a "plan to watch" list. Gah! That's why I remembered it all wrong! xD

Anyway, I just wanted to thank everyone for helping me find this movie, you're the best! : D
