Suguru just got back from a solo mission, but he didn't return normally. He came back small and had cat ears and tail and still could use his cursed technique, curse manipulation

when you (Satoru) Suguru best friend, so when you found out, you would not leave him alone no matter what

Here you are now sitting on the couch and Suguru in your lap, feeling comfortable and safe with you. Suguru was in your lap purring and slightly looked at you and mumbled

"I'm comfortable like this, Satoru"
