Yep I totally feel the same as you guys, I cannot be dealing with age gap in manga, where an adult is cracking onto a high school kid! It's got way too much of a 'grooming' vibe, no matter how much some mangaka try to make it sweet or cute. Actually, I don't like a high school kid cracking onto an adult either, when it leads to sexual contact. I'm an adult myself, so it's just gross and wrong to me. I get why a high schooler would have a crush on an adult, but it's always like, "What the fuck is wrong with that adult?" A uni student, particularly over 20, is fine though.

Something is definitely off somewhere - in a later chapter it turns out he IS in high school. I was bitterly disappointed. And whyyyyy?? There's no reason for him to be a high schooler, the plot would work just as well with a uni student. Now, as far as I'm concerned there's something wrong with the guy for falling in love with a high school kid. The only thing I can think of that could redeem the story is if the dude moves out to give the kid a goddamn break, and there's a time jump to 5 years later when he walks into the restaurant where the young guy is working. Or something like that.
How old was uke again?
