@Big_Boss I mean, she was sort of a tsundere and there was a smidge of “drama” with the coworker that also likes him. There are plenty of manga with fast romance and no drama. This isn’t the only one. I really do like this manga and I think it’s enjoyable, but “realistic” isn’t the word I’d use to describe it. Romance manga wouldn’t be entertaining if they were realistic.
@liquidsword, I get what you say, but what I meant was when she was "tsundere" it was later at same chapters portraited how she had suffered from the way she dealt with situations, regretting it, usually it's just brushed off as part of story. Basicly what I say is this looks realistic enought to be believable.
