takeru was a straight guy before liking shima, so no, we can’t say that he was responding to the flirting if he doesn’t even think that daichi was flirting to begin with. also, it’s not as if shima knew just how big of a burden daichi’s love for the manager is. remember, the only people he was opening up to were tamotsu and the more experienced guy. so with makoto giving that info referring to it as weakness, shima could’ve thought that it was merely a crush. shima also doesn’t know about the manager’s personal life, he doesn’t know that the manager can’t reciprocate daichi’s love. so daichi wasn’t outed because shima wanted to embarrass him, it’s just that shima, not being close with daichi, resorted to the only info he has of him to make him stop.

First off, they are not in a relationship. Secondly, if they were in a relationship, it's still up to the person who is being flirted with to deal with it, not his partner. The one being a bitch is the person attacking someone irresponsibly just for verbal flirting. If he is insecure in his relationship or lack thereof, that's his problem - he can't just take it out on others.

Like I said, doesn't matter either way. The one to react should be the one who was flirted with, in this case Yamashida. If Shimada has a problem with how Yamashida is reacting, then he should take it up with him. He should either trust Yamashida or clear things up with him. He has no business attacking or bullying Daichi.

Yeah, we're never going to be on the same page. There's nothing wrong with Daichi's behavior. If you can't trust your partner to handle even that amount of flirting, then that relationship is just sham. Are you going to follow him around all day chasing off anyone who might flirt with him? Men / women who go to battle with others in such an underhanded way for flirting with their partners instead of trusting or ensuring that their partners don't stray, are just desperate and insecure.
Don't want to be a outted don't flirt with the bf, so simple. Thus wasn't the first time either.
He was being an ass and I'm glad Shimada didn't take it. He was probs being looked down on because he's a cutie pie. I'm glad he spoke out and drew his line.
