I honestly find this manga to be quite twisted. It would have been better if the younger brother, Yukitara, just not realise his obsession with the MC, Yukinari. Instead, after being found out that his feelings for the older brother was wrong and would just get approval for his brother’s happiness. Having a bro-com isn’t bad, but just don’t go too extreme that would destroy all family relationships. Although Kazusa has been blackmailing Yukinari, as long as he realises his obsession and possibly love for Yukinari, then I think it would be great. Although, there are lots of drama during the plot such as gang rape, rape, child abuse...all psychological type. But the ending kinda tied up well. But I will not be likely to re-read this.
