He only gets worse.You can read the other chapters on raff manga. It's translated. Only when he has thoroughly destroyed their relationship and she becomes so depressed her eyes look dead does he realize what he's done. And yes it will be completely ruined. Say goodbye to the cuteness.

The ex is totally an asshole so far (except for punching the twit in karaoke). But she's acting like a jerk now. Not answering Hayato's calls is being as rude as her ex in my book. She's being MEAN. She may not mean to be mean, but that's exactly how she's behaving. Cruelly to a very, very, very sweet and nice guy. I'll take a kind, upright guy over a hot jerk any day. But this heroine is making me crazy being so stupid and cruel to Hayato.

True it is rude to not answer a call from the person you're going out with, but the Asshole literally stole her first kiss even after she clearly rejected him the first time and tried to the second time. You can always call back the next day, but you can't get back a first time. (︶︿︶)=凸

I don't think she was going out with hayato at that time... In the later chapters she mentioned that they weren't dating. Also I don't hate takato. He just didn't know how to show his feelings and kept to himself a lot. He really liked her and he still does. He didn't mean to destroy their relationship. He was fighting for his love just like her fighting for her love and hayato fighting for his. (although he didn't really do much in the beginning). Can't really hate him. She was also at fault when they were in middle school. She kept to herself a lot too and gave up.

Oh if you read the later chapters on raffmanga, she becomes like the ex with her actions, her feelings and yet she doesn't even see it herself. She still doesn't even understand her ex. BUT if you read on... Spoiler..
They never really broke up with each other face to face. She only heard him say it to his friend and she started to avoid him. He is still holding onto her.
Wow... All these comments about the Ex. We're forgetting that SHE DIDN'T LIKE HIM! Just because he's hot doesn't mean he's not an asshole. He forced a kiss on her. Bad boy whatever nonsense, it's still morally wrong! Even at the end of Chapter 8, she's CRYING and in depression over seeing her ex.
Hayata is so cute and pure. I really want him to end up with the MC. The scenes so far has made him a breath of fresh air in his honesty and chivalry. He makes the MC become a better person! It's refreshing to see the girl pursue the guy. Their love story is so precious right now. He doesn't see her as a doll but in her bold personality. Takato will just revert all that back to being an emotionless doll if he ends up with her (my predictions).
