hello, does someone remember the name of the manga about the mangaka that made the manga or was an activist in real life, is was about this guy that was in love with his friend and let his friend stay in his house but his friend was always calling his girlfriend and he got really angry at him because of it, and maybe his friend said that he doesn't know how he feels because he has never been in love but the guy got angry at his friend and left his house.(maybe the last part got is from another manga and got confused)
