The Yandere Younger Brother Has Great Tricks

[Forced love + White cut black brother + yandere and paranoia + younger age + seven-year age difference] Shirogiri Kuro's yandere brother VS mature and sober sister Wen Ying always thought Gu Fei was very well-behaved and sensible, and she always treated him like a little brother and took good care of him. Gu Fei asked cautiously: "Will Sister Wen leave me?" Wen Ying answered with certainty: "No, Sister Wen will never abandon you and will always be by your side." But she didn't know what kind of heart Gu Fei had hidden behind his innocent and well-behaved appearance. "Does Sister Wen hate me?" "If you don't hate it, then you like it?" Under Gu Fei's step-by-step temptation, Wen Ying fell deeper and deeper into the trap. Have you really fallen in love with him? Impossible! Wen Ying realized that Gu Fei's true identity was a complete devil, and she wanted to escape! Must escape! Since you fell into the hands of the devil, how could you escape easily? Every plan failed, and Wen Ying was locked in a luxurious room with nowhere to escape. Gu Fei asked: "Sister, do you know what the price of running away is?" Of course she knew, but she didn't want to be around a devil! She doesn't want to endure endless torture! Wen Ying's eyes were full of despair, and she asked in a trembling voice: "Why are you doing this to me?" Gu Fei gently stroked Wen Ying's face with his fingers and said in a calm voice, "Sister, if you don't behave, this is punishment."
