Billy and Mr. Yu are diffidently dating 100% and there's no denying it. I was getting suspicious of them when Mr. Yu was talking about when Billy got drunk cuz why would they go drinking alone...Overall though i loved this story and the art was beautiful. (⌒▽⌒)
Omg if he just picked someone else to date that WASN'T someone he met as a kid then she wouldn't be involved.
