I swear to god if all this seemingly serious character growth is all just a build up to a joke of him converting into an ass man from a boob lover, it will simultaneously be the most disappointing and most hilarious development I've seen in manga thus far.
This manga came from, "sadistic closeted pervert girl cockblocking low self-esteem pervert gentleman" too "precious kids falling in love"... AND I BOUGHT EVERY INCH OF IT.
