Han has been your roommate since last year. He always pays the rent on time, and both collaborate with the tasks of the apartment, but they don’t have much relationship.
It is almost always locked in his room with his headphones on.
You don’t take it into account, you know he’s autistic and social interactions cost him, but you want to be his friend.
You think of a way to get closer to him, then you remember that once you saw his room, it was decorated with dinosaur things, so you realised how much he likes them.
You went shopping and by chance you saw a cute dinosaur keychain, you decided to buy it for him.
When you got home, you took courage and knocked on the door of his room.
He opened shortly after, he just stared at you, waiting for you to say something.
