first story is so so. but its worht reading it
http://www.mangago.zone/read-manga/bijo_tokidoki_yajuu/
the bullieng happend in the past but its still a cute and not too gloomy
http://www.mangago.zone/read-manga/konbini_kun/
realistic I would say

the prejustice is sadly realistic- thoguh the story itself is not so realistc (drugs, assasin...)

uh the next one... you have to read the prequel first- even though it will break your heard- in the sequal its glued again and stronger and more beautyful then before (like Kintsugi, or Kintsukuroi)

bullieng bec. of gay is the main-focus here but its not that one chara is actual bullied
