Fukufuku Heights
Cute and short but pretty plain. Slice of life shounen ai, *almost* without any evidence that the characters are even dating.
Sono Futari, Kaishaku Chigai desu!
Meh, comedic 'what even are feelings and dating' BL between childhood friends, plus 'surprise, we're both otaku' subplot.
Mitsuya Sensei no Keikakuteki na Edzuke
EXCEEDINGLY WHOLESOME!! A bit like Old Fashioned Cupcake, and a super sweet slice of life. There is no sex here, just a wholesome relationship!)
Number Call
Very wholesome friends to lovers shounen ai.
The Two Lions
Cute! Almost no actual romance content, mostly focused on becoming friends and then catching feelings. No gay panic! A little lacking in resolution.
Mizu No Haru
Ummm.... I don't like the lie the one kid used about his "dad" molesting him, and then the manga panels from his POV ALSO implying this, despite it all being a fake lie. It's a gross trope that really sours the otherwise fluffy vibe of the whole manga. The writing is also very loose and the art confusing - lots of same face and same hair lol.
Shinyuu no
A cute little friends to lovers plot, plus mutual pining/unrequited love. Not as peak as my absolute favorite one of these, but in the same vein, and with a similar confession (though less dramatic).
Seishun Radio Pinchers
Interesting unique setting. Kind of low energy though? It had some good romance development and it's nice how much the robotics theme is focused on. Very wholesome
Takara no Biidoro
THIS IS SO CUUUUUTE. Very wholesome college relationship about two people catching feelings and then catching even MORE feelings while going out. I especially like what Takara says about allowing feelings to grow after starting a relationship. So mature and thoughtful.
