Sumi deserves to be happy. http://www.mangago.zone/read-manga/mimurake_no_musuko/tr/1039...

i was thinking so too. he rly deserve a happy ending now. i thought the whole time that his lil bro was his first love but it was rly oomiya huh? bc he said his first love was lost. still he is getting calmer now i guess since he has a stable job now. hope he has a sexy boss who can bring him to be faithful and forget his past ( even so it never rly was cleared what happend to him at that mountain, but i guess he was badly violated).

I don't see the heartbreak...? W.
