Wowie so aggressive o.o I think his just testing his resolve. Sure its not nice but its necessary for a strong relationship to be tested. It would be stranger if no one said something. Since theres always that one guy that does the "bad guy" act (〜 ̄△ ̄)〜
I know that he's just worried but for him to say that to mikami (/TДT)/ (/TДT)/ (/TДT)/ i wanna choke him so bad (/TДT)/
