Absolutely appalling decision. Why did the author decide to ruin his own story by using one of the worst and most overused manga tropes that far into the plot? How does that make any sense at all considering the audience that typically read series like this? The only people, for the most part, that even enjoy genderbender stories like this are the ones that seek them out to begin with but this isn't even advertised to be one of those.
Honestly wish I had just read spoilers first so I didn't have to waste time getting invested in the first 30 chapters just for the author to pull the ol' loli morph maneuver. I even thought that it must just last for MAYBE two arcs at the most, turns out its for the rest of the series, I have never dropped anything so hard in my life. Yes i'm mad.
