Honestly I'd just think that my friend was kinky and leave it at that. I think this dude was really weird to confront him in his home??

Honestly same. He bit him when he was a human so it's not like the bit mark looks like a "monsters" doing. It doesn't really make sense. (〜￣△￣)〜

Ikusabe said something like, "He's got good intuition" when referring to the friend so the friend is most likely relying more on his gut than actual reasoning. And when you have a strength in something, you tend to rely on it a lot, so that friend probably jumped to conclusions without looking at it at another perspective (￣∇￣")

My conclusion would be my friend is a kinky bitch

Haha ε=ε=(ノ≧∇≦)ノ
