Kamiato Kara, Hatsukoi

“Even though I don’t want this, my insides are throbbing.” Rika (omega), who got raped in the past, got bitten on top of that by someone whose face he doesn't know. Because of that, even though he can’t have sex with anyone else, his heat makes his body ache... In order to overcome such a cursed nature, he desperately acted like an alpha and was somehow spending his college life peacefully. However, one day, this person who had a memorable scent, saved Rika who got attacked by alphas while being in an unexpected heat.
