I'm sorry, I couldn't go further than chapter 24. It's just...
Ew... I guess it's cute but the age gap 26+Minor is killing me slowly. Worst is, do we ever get Makoto's age? Maybe later but still.
I know it's actually subjective but I don't feel sane reading that. Up to ch24 (without wanting to spoil too much) most character's approved of said relationship, even cheering for Yamada to get beyond third base. And He's the only one thinking "Hey, that's bad, I could get arrested"... Yes. You should have been arrested bro. This isn't a college student x office worker. This is underage girl and grown ass man.
I won't say it's grooming territory but damn, that's a disturbing one to me. Probably due to the author framing it in a better light than it actually is.
