How about this, pretend to be her brother for once like color your hair black, use his perfume, masks and etc. Impersonate him to the point she doesn't know what changed. now let her jump you and remove your mask like after a year of training.

The brother isn't into incest

So basically from what I can see or pick up on, the girl finally couldn't hold on any longer and impulsively decided she wanted to have sex with her brother, yet when it happened, the brother couldn't get into it, like his love isn't that kind of love, just family love. And the yandere guy seems like he finally snapped, like "why dont you loves me," and then he lets her take his life if she hates him that much, by choking him, yet she can't do it, and it ends there... but yeah, that's just my speculation. I'll be waiting for the translations though. If its NTR then i drop it, kinda rooting for the yandere guy

God damn it feel like NTR @@
