Two things:
1) MC is a weakling and that is pathetic. I hope it has some self improvement, like joining a sports club or going to the gym, otherwise it will be trash.
2) it is the first time I see a manga actually addressing the problems of divorce. I should be satisfied with that but it would be amazing if he actually came up with a way to make his parents reconcile.
That said, my parents are not divorced so I don't really understand the mindset of people involved in this kind of drama. I just find it extremely unpleasant and it would be more heartwarming to them fixing it, which you almost never see in media.
Personaly, if my parents ever divorced I would talk to neither of them. They always taught me to not trust in people who break vows, so that would apply to them too.
