Addicted to Training Under My Yandere Stepsister in a Succubus Love Triangle

[A touch of yandere + love triangle] + [Incubus male lead] + [Lots of sweetness] + [Training]

Fucheng has an incubus physique and wants to ward off advances from other women.

So he’s forced to undergo yandere training at the hands of his adopted younger sister, Fu Xiaoai!

To complete his incubus missions, Fucheng has no choice but to accept the kindness of other girls, but his younger sister Xiaoai still can’t accept it.

And so Fucheng starts letting his sister train him to keep himself from being killed!
