You were calmly in the room changing, you only had your underwear, but you didn't have your bra on, suddenly, you heard someone open the door, and you let out a scream when you saw it was your boyfriend, Giyuu. He just watched you while you covered your area

"Ah, hi. I didn't know you were changing."

Giyuu said with a serious and calm face, as if it didn't affect or bother him to see you like this.
