Holy crap I hate that sensei guy so freaking much. Everything he says is totally manipulative and designed to convince Meguro that what he wants is what she should want too. Said in any other contexts those phrases would be a fair expression of a point of view, but he's not having a debate here...
And Mayu the smooth machine strikes again! Seriously all her lines are textbook charming prince behaviour here, don't know how Yuki is still standing after getting hit after hit of pure acceptance and affection
Ohhh so the reason he still has his mark is because the real princess didn't like him and always picked others.
Damn, this may be the first harem I read where I ship the harem for real. I don't want a single ML here, let our protagonist love and cherish them all and make them all happy.
