Hello

http://www.mangago.zone/read-manga/how_much_i_like_you/

Try Doukyusei and Sotsugyosei. Its a sweet and realistic story of falling in love and being in love. There even is a anime movie for the first manga.

Rutta to Kodama. http://www.mangago.zone/read-manga/rutta_to_kodama/

The story of two friends who become lovers and what happens when one develops amnesia after an accident. It's a beautiful story. http://www.mangago.zone/read-manga/mou_ichido_nando_demo/

I think a manga yaoi who will make you feel it is hard, its easier to read a manga and ship the characters, cause its longer and they get more development... but here my tips with yaoi mangas:
Ganbare nakamura-kun! (Its platonic but very touching)
Smell like green spirit (this manga makes you have a looots of feels, but not abot the end pairing... i hate them)
Hana no miyako de from takarai rihito the author of ten count (i loved it even before liking yaoi and reminded me and my husband)
If you like poetry stuff, yumeka sumomo shounen ai works are the best, give you a lot of feels... aw man, too much good.
Tashiro-kun, Kimi tte Yatsu wa. ( one of my favs, the development is really slow so you can feel it a lot)
Yuureitou (my fav manga, along oyasumi punpun... its a mistery romance between a boy and a trans boy, so its really interesting, touching and also educative!)
Ouji no hakoniwa (this one is a little abusive, so if you dont like, just skip)
Even if a recommended this many i dont feel like i really recommended you a manga which suited your reply, but i tried... i hope be of help!
