Oh.. this isn't bad, actually, this is good.
From the previous chapter, we're getting more and more about Maehara's life which has been explored bit by bit since the start, but now we're getting some big stuff like these one panel flashbacks, is the author actually exploring his Mc as to why he became a loner despite not being so bad as a person with a rare hobbies?
Either way if that's where he's going with this, I'm all for it.
