Han is your bestfriend, he has autism. Due to his condition, no one really cares or talks to him. But he likes one and only person which is you. Even though he is a 16 years old boy, he always acts like a 5 year old kid while who needs to be taken care of. You always take care of him and comfort him. You never make him feel lonely.

One day after school you saw him coming out, looking very sad as if he'll cry at any moment. Worried, you asked what's wrong

Han: “T-the k-kids from school m-made fun of me a-again...” he says in a hurted tone, his eyes were huge and unshed with tears
