I hope that Sei is just trying to justify his mom actions and nothing else pls. I don't think that Oshimi is gonna fuck this up implying that Seiichi all this time have been the cause of his mom being like that cuz at this point that doesn't make sense.
Clicked this chapter randomly just to see how good is the colored version (which is amazing) and without realizing finished the chapter... I really wish that Togashi have mercy on us and get to draw again.
