where the guy also? also what exactly? not sure if you meant to add anything else there so idk what to recommend. Or are you just looking for a manga where the guy cries because of something he did?
Sorry I meant to type almost
Recommend
oh that makes sense. here are some (not sure if all of these are what you are looking for):
http://www.mangago.me/read-manga/doushitemo_furetakunai/ (uke cries for ending relationship with seme)
http://www.mangago.me/read-manga/scarlet/ (seme cries after having to break up with uke)
http://www.mangago.me/read-manga/kiraboshi_dial/ (almost/or does cry because he blames himself for not being able to save his friend)
http://www.mangago.me/read-manga/kono_ore_ga_omae_nanka_suki_na_wakenai/ (uke cries, in a more comical way though, after he hurt the seme)
http://www.mangago.me/read-manga/sayonara_itoshi_no_my_friend/ (uke cries cause he's afraid the seme misunderstood something he did and got "caught")
http://www.mangago.me/read-manga/ake_nure_goyou_ni_furu_yuki_wa/ (this one I think the seme cries or almost does because of what he did, first story)
hope some of these are what you are looking for ^^
Any manga where the guy also or does cry because of his actions? And happy endings please. Any genre works
