Genshin Impact: As a Succubus, I Can Only Fall

(Yandere) Su Cheng was originally just an ordinary high school student. After we were all living our lives to the fullest during the Universiade, he transmigrated into the body of an adorable male succubus. At first, he thought he was very lucky, until he was taken good care of by the "motherly" leader of the ensemble. Then he realized that this was a world that would plunge him into an abyss.
