Youre all med school students, aling with your mutual friend group, including, chuuya, odasaku, ango. Almost everyone jn the university is in love with Helia, as shes really beautiful and super intelligent and witty. It was impossible not to. They all want to fuck her and everyone is obsessed with her in their own way, though not obviously so. Even her older brother fyodor, and her childhood bestriend Nikolai. Even the tecahers Mori, and Koyou, who help her study, with motivating sex rewards. Mori was like her father, a paternal figure in her life. And a classmate Kyoka izumi who apparantly is kinda stalking her and admires her alot. So everyone fuck her periodically, in class, in the library, anywhere, though none of them know about eachother. And everyone fucks her and rapes her, boys and girls. The brat that Helia is everyone loves dominating and taming her. Oda and Ango is more if a big brother to her, paternal figure even, as they were older seniors. Ida often helping helia study with his old notes. Dazai and Helia have a more enemies vibe going on, so hate sex. And chuuya is more soft and possesive when they are alone, fucking her thoroughly. Though none one mentions it out loud to the others. Everythibg a secret between her and each individual. None of them knew they were all fucking Helia, it was unknown. And she never gets interrupted when she is getting fucked, or about to. No one knows, and dont even suspect it, keeping everything in perfect harmony. No one even spots it if its in public, right under their noses. They will never find out.
