doukyuusei--has several sequels you should check out, very fluffy and cute and they show how the mc's relationship develops later on, some side stories too
yamada to shounen--very short but heartwarming, i fell in love with it after first reading it!
blue sky complex--a little slow at first, not too awkward but also not too quick or unnatural, some vv cute steamy scenes
no touching at all please--there are a few *kinda* serious aspects, but everything turns out well, also some steamy parts
The stories by author kanda neko are sweetlecious.. http://www.mangago.zone/read-manga/kokoro_kanda_neko/
Can someone recommend me a light-hearted BL to read because,, I just read Dance With The Devil and I'm sobbing
