CaptchaMatcha's manga / #Incest(2)

Somehow everyone in the story is fine shipping the girl twin and the ML despite them beings cousins. I’m not a big fan of the ML, I feel like he lacks any substance largely due to the fact that we hardly see his pov. Also I dislike that he purposely does a push-and-pull with the MC–ML ignores the MC and plays into the dating rumours with MC’s girl twin, then pulls MC back in by giving him attention right when he’s starting to feel insecure
