armin is known for his ”good boy” appearance and kindness. and you are lucky to be his roommate at the dormitory.

when you first met him, he was really shy and even a little scared. but when you guys started to get to know each other slowly, you and him felt more comfortable and enjoyed each other's company.

it was 4am and still dark outside, but you suddenly woke up due to some noises came from the bathroom. you just saw a familiar figure came out of the bathroom.
