Good BL with side couples?

https://www.mangago.me/read-manga/smurf_s_world/ (both couples are good but i loved the 2nd one more)

Thank you I'll def check it out!

Serious joke and Love so pure have really cute side couples that get a lot of focus.

Try this!

These are my favorites side couples(づ￣ ³￣)づ

Thank you! I read Love so pure - the couples were really nice but the size difference especially with the second couple made me cringe a bit haha even if their story was fun.

I'll look up Serious joke now!

This is fantastic, thank you!

Loll agreed the size difference was a bit much

viewfinder (ez) I guess it's not really a side couple more of a second couple

recently caught up with this and the couple development is rlly good (though the 2nd couple is currently on their development arc). there is noncon but not between main characters and is treated as such, no romanticization.

Thank you! Second or side couple either one works as long as they get proper development

Thanks so much I will look them up!

Oh I really like the art here and the premise seems interesting thanks so much!
