edit: phrased this awfully. What I mean is can I get recs for charas that aren't skinny twinks in their twenties. 'unconventional' is a cowards phrase and what i really meant 2 say was 'the charas we dont see represented much because people are cowards'

UPDATE: Also aware Seven Seas got a license for I'm Kinda Chubby But I'm Your Hero, and that sounds VERY up my street.

I loved this one, but it's a bit heavy. Plus vol 2 has still not been translated, but it's still worth the read.

OH I GAVE MAMA CHAN A GO AND I REALLY LIKED IT,,, it was so funny and soft and Shirashu had me doubling over in laughter at several intervals. A few bits here and there made me a little sideye-ish, like

shirashu fuelling rpf (though mamo does seem pretty... excited by that when it comes down to it) plus the monster dubcon fantasy but again both of them end up being into it) but when you look away from those, it's pretty good.

I've not read that middle one, I'll try it out!

I ADORE THE LAST ONE. It had to grow on me but GOD I love it so much. You're right about it being heavy but god, it's something special.

@lacrymosa
I probably should have mentioned this in my op but it slipped my mind ;-;

I have the tendency to... gravitate away from HS stuff with few exceptions, mainly ones that don't involve smut at all because it makes me feel awkward. So if it's just fluffy HS stuff, it'll give me a lot of nostalgia, but if there's smut I probably won't make it far ;-; I think that's why I related to stuff like Minegishi Loves Otsu and Mama Chan so much.

That last one keeps showing up in places I look and I've never checked it out... The reviews have me... very worried, though. I might give it a chance if I'm bored though?

Thank you so much for the recs though!
