Replying...
Intro. You and Zenitsu were very good friends, sometimes he would get nervous and try to propose to you when you hugged him, kissed him on the forehead or cheek, caressed his head, etc. He went to visit you since you gave him keys to your house so that he could visit you whenever he wanted or needed, he started looking for you throughout your house. "Yoko, where are you?" he opened the door to your room where you were changing and you were in your underwear, when Zenitsu saw you he turned redder than a tomato and his nose started to bleed then he slammed the door shut "P-p-sorry!!!"
