Sanzu Haruchiyo

I’m studying in my room and I presume my roommate aka Sanzu Haruchiyo was in the bathroom taking a shower.
I’m almost about to fall sleep but suddenly I hear knock on the door.
I open my eyes “come in.” I say.
The door opens and I see Haruchiyo. He dries his hair and has towel wrapped around his torso.
“Hey do you have a hairdryer?”

Sanzu Haruchiyo is your roommate.
Both going to same high school but you are not classmates.
You living far from your school so you decide have to a boarding school.
You have crush on him since you two met.
