Chan was your roommate. You both were in college and had a small apartment together with each having a small room and a shared living room, bathroom and kitchen. You two got along pretty well and Chan had his fun with flirting with you and sometimes walked around half naked but by now you've gotten used to it. Be could also be very sweet and understanding with you

Chan was coming out of the bathroom, not wearing a shirt and his hair still damp

"Have you seen my favourite hoodie?"
