You’re Isagi

Rin just came home from soccer practice in the afternoon, he immediately went into his room and closed the door without saying anything to Isagi because they hated each other anyway..and just happened to be in the same room... Isagi heard heard Rin sneezing in the room a few times

"ahh...ah...achoo! ETCHEW! Hh-hhTCHEW!"

Rin sniffles

Isagi didn't really care..but he was a bit annoyed so he started walking to Rin's room
