Made the mistake of trying to read this, never again.
The fact that the MC is supposedly male genderswapped into female/ his ex girlfriend (questionable) has absolutely zero bearing on the plot.
the girl (now turned male) is like an immature teenage girl's idea of a cold, dark, and handsome man except its just some idiot who refuses to communicate and got with that guy in the first place because he was 'easy to order around' (her actual words almost).
In the second chapter its explained that the MC's best friend was trying to sabotage his relationship the entire way even since day 1. This 'best friend' was apparently also the one that caused the breakup itself because both the MC and the girl think its the other side that broke up first via a text and theres other details that don't line up.
And you'd think that they should have talked about that and the MC does actually (to his/her credit) try to bring that up but the girl literally just refuses to acknowledge it, saying "can you please stop misunderstanding" when he never even explained what he understood in the first place. (even after she already said that she knows he's easy to manipulate), like no suspicion at all? thats idiotic not 'cool'.
Later after they get swapped its revealed this 'best friend' of the mc kept talking to the girl every day basically asking her to break up with the MC and instead go out with him. And the girl refused him every time. Except she literally never mentioned it to the MC himself.
When the MC asks why didnt she tell him about it, she says literally " Nothing would have changed even if i told you, right " and the MC just goes 'she's always been like this' and just accepts it like "fine, nevermind."
So she 1- knew he was easy to order around, 2- that the best friend wanted to sabotage their 'relationship', 3- never told him about point 2, 4- still didnt think that breakup over text was suspicious and refuses to actually communicate.
Later theres a scene where the MC is dressed in a lame uni jacket cause he/she cant pick good clothes seemingly, and then the girl (in his body) walks up dressed all fashionably and draws everyone's eyes. So i get that the scene is trying to convey how 'cool' she is, but if you ask me she just comes off as basically a dick? She was in a 'relationship' with him but never once made him dress up properly?
Anyways to sum it up TLDR; absolutely do not read. stupid story, MC actually doesnt have any friends, even the 'girlfriend' was fake, an immature teenage girl's idea of what a cool partner would be like except they're just a jerk who refuses to communicate at all.
