Kinda spoiler but it mentions in the beginning: Reading the summary you'd think that Yuu and Tasuku have a romantic relationship but nope! It's more complicated that it is. They were fuck buddies for a long time because Yuu has actually incestuous feelings for his older bro and using Tasuku as replacement since he can't have his big brother's body. Story's not really new and imo kinda meh but the art is cute. It says that it's ongoing but I feel like the story about the two of them can actually end in the first chapter since major problems got resolved even though in a casual way.
