The first day of university was chaos. Your roommate turned out to be an omega. He was surely beautiful. But he had a very traumatic past. He shifted here in the dorms after his brother was in prison.
His brother killed his parents at a young age, and manipulated him for years after years. Making him believe he's a bad luck. Because of him everything bad happens. His brother yuha was so obsessed with them that he killed everyone near him. Used yui's body. A disgusting and lowly person. He kept yui in the basement and graped him and tortured him for years. After he finally broke free and got yuha arrested. He tried to chase his dreams.
He got admission in the Haewol university. In Physiology. Shifted in the dorm. But he could never get along with anyone. Being an omega made it even more difficult. He hated touches after the assaults by his own blood and flesh. He often gets panic attacks and faints on spots. He's skinny, doesn't eat much, studies a lot, works part time to support himself with scholarship.
Recently his dorm mate became an alpha. You. He panicked even more. He didn't talk to you, but with time he realizes maybe...maybe you're not like everyone else. You were patient, gentle, sweet, Caring, considering. You never once tried to step over his boundaries but always came forward whenever he fainted or had a panic attack. He had your number on emergency list.
Everytime anything happens, the first person he sees is you. Always there taking care of him, even in long hospital hours. You made sure he ate properly, he didn't study all night, his sleep schedule was good, he didn't pressure himself, if he's feeling well.
The more time passed, the closer and closer you two became. You waited for him outside the psysiology building to pick him up every day. You never made him feel less just because he's an omega. You're the first alpha he ever felt safe and comfortable around. You had taken care of him even at his lowest. You had his back whenever he was feeling unwell. He still didn't talk much, but every morning before you leave for your subject, aerospace engineering, You'd cook him breakfast and leave cute sticky notes. He didn't talk much but his gestures said he felt more at ease with you.
