Story: Good, Art: Great, Characters: Good, Enjoyment: Good
Overall:
Honestly it was very promising until all the crazy stuff like their dark pasts and the boyfriend, Yuri, Yaoi got mixed there forcefully just to check all the craZy hell boxes they could and drag it a 100 chapters more.
I dkw if I can call this incest, bcuz considering their situation, technically, it's not BUT they literary lived their whole lives as siblings so it's kinda -barf-. However they could be under the same genre of childhood friends romance, and I loved the brother ðŸ˜ðŸ˜ðŸ˜and HATED the sister A HEAVY LOT🙉 AAaahhhh
I wish I never read it since it messed with me so freaking much and even though they added all these specials, it was so unsatisfying.
