Please Help Me Find This Manga

I want to read a manga where the mc like to see her/his lover to suffer and come back to her/him each times. It could be Yaoi/Yuri or straight relationship.
Plz recommend if you know any.... ╥﹏╥

fell asleep while reading and browser redirected to lady-first so I cannot remember the title. it is about a guy who hates unrequited loves (bc he witnessed his brother be heartbroken over one) so he calls out this guy who is obvi in unrequited love and says he'll help him. they are both in some club called travel planning club or something and there are only 3 members.
