Definitely not on this site. It's some girls who coincidentally meet and they both like black rock shooter. There is a lot of drama I think and it's read left to right. Sorry for the lack of details
oh, I've read this one.99% sure it was chinese manhua. One of the girls was on holiday trip with her very strict parents, she was interested in black rock shooter and was drawing some fan arts if i remember correctly. She met the other girl during this holiday, in a manga shop or something. Her parents were opposed to the friendship with the other girl. I think later on they met at school, but indeed there was some drama with her parents trying to plan her life.
Aaaand i can't remember the title.I've looked through different chinese and korean manhuwa/manhwas but can't find it at all.
I'm glad you're here to fully explain the details
