This IS wholesome and cute. It's not about "DEM UNDERAGE KIDS AM I RITE??", it's about puppy love. And just because something is cute, it doesn't mean it can't have its gross and self-aware moments too.
It's like some people in this comment section didn't even bother reading past the first chapters before judging, which, considering it's the Internet, just might be the case. I mean, how can you miss the main character's struggles and self-awareness? Did you fail to see the word LOLICON being mentioned more than one time? The bleak and angsty panels in the later chapters? "Y'all need Jesus". Yeah, maybe. And you need reading comprehension.
Anyways, excited to read more from this author, and I hope her first anime adaptation goes well so that this may get an anime too someday. One can dream, right?
