Same! I thought he overreacted a bit considering Dohu's personality. If Dohu only wanted to use the ML, he would have acted a bit differently, don't you think? He clearly thinks of things a bit differently than most people, which ML should have picked up on by that point.
But reading some of the comments here, there might have been more to it...
Well there's that but also what writer doesn't take experiences from life and people they know? That's literally how they write stories that's why I always thought it was a dumb argument. And now it's just a misunderstanding cause he left for another reason but if course Dohu doesn't know that so he thinks it was their fight and has clearly been beating himself up about it for years, but don't show back up and act like you don't know me when you clearly do. （￣へ￣）
I still think that fight from before was stupid and even though the grandma or aunt or whatever is the real reason he left Dohu doesn't know that he thinks it's still because of that dumb fight. I would act like I don't know him either two can play this stupid game （￣へ￣）
