ReviewRaptor's manga / #Wrong Coverart(1)

Not the best, not the worst. But I have one issue right off the bat: The start is pretty shitty tbh. Leaving someone for not giving you enough attention (basically what it boils down to), even tho you don't have the decency to at least ask why the other party behaves the way they do is just shitty. I get the whole being suspicious thing, but it didn't come across in a 'I'm worried they might be cheating or whatever' sense the way it was portrayed here. Maybe the writing is just bad in that regard, but it's an overall really shitty type of thing to do. And while the author tried to make this more realistic by bringing up the 'are they really bad because I felt suspicious? Or is it me?', it wasn't portrayed well enough to make me feel comfortable with the MCs side of this arguement. He's dislikable af if that's his go-to logic in this situation. Besides...nobody is perfect and he clearly didn't care enough to ask personal things despite thinking/saying that they are dating. So they were basically just the fuck-buddy kind that goes out eating too. And that makes his 'no attention for me? let's break up then, lel' even worse then...
