@Lex79 Cause fucking beta cucks, man.
Haven't you read? Everything's the male MC's fault, always. He has to know everything, understand everything, get every hint and make the first move. Women are apparently incapable of such things, nor are they expected to do them.
So Igarashi's relationship doesn't progress cause Takeda's a dense beta cuck. And Sakurai's relationship doesn't progress cause Kazama's also a beta cuck. The girls play no part.
At least that's what like 90% of the comments say.
