So he basically went on a date with a girl and acts like he has done nothing wrong but shouts at girl because she has done the same (what is worse is that he was the one who confessed). And he forced himself onto her??
It would be good drama if those parts were addressed but knowing this manga... It will go past that as if nothing has happened.
And why no one is talking to each other, he himself said that last relationship didn't last because he continuously went on a dates with girls while having a girlfriend. There is no reason to trust him that he is serious.
