Grital's manga / #Shounen Ai(130)

So the first story is fine, the ML seems to somewhat repent and while the MC faces loads of hardship it doesn’t all seem directly caused by ML (tho plenty definitely was or at least could have been prevented by him), the second couple involving their son however…. He’s just an over grown child and I have no idea how he grew up like that when his parents were so aware of what that kind of personality leads to. His ‘mother’ the previous MC just doesn’t get involved at all despite his son being a bigger as than the previous ML who was at least capable. So I don’t think I’ll continue cuz I seen a spoiler about the ending and I can’t be bothered. This new ML doesn’t deserve to be happy with the new MC at all
