Please, I’m begging you to help me find this manhwa. It’s a mature-themed story with elements of school life and smut . The plot revolves around two female college students who frequently talk about their sex lives.
The main female lead has purple hair and is obsessed with BDSM . I remember that she used to cheat on her boyfriend (who has blond or ashy-gray hair) because she didn’t feel comfortable sharing her BDSM preferences with him. However, I believe she eventually stays faithful to him and they become the main couple.
The second female lead, who is more of a supporting character, has short blonde or brown hair. Her love interest has black hair, and their relationship started after they got drunk and had sex , despite just being friends. One memorable scene involves the couple arguing in their apartment, where the girl locks her boyfriend out on the balcony, either as a joke or a bet. He ends up jumping over to the neighbor's balcony, entering through the front door, and they end up doing the deed again.
I also remember the boyfriend of the second female lead possibly has a tattoo.
The second couple was just too cute, and I really want to reread the manhwa. If anyone knows the title, please let me know!
