After Falling Out of Love, My Yandere White-Haired Sister Wants to Support Me?

[Single female protagonist + slightly yandere + fun jokes + relaxed and funny + cheap male protagonist + no system] Shen Bai, who was born as an orphan, works hard every day to live! It is said that life is bitter first and then sweet. He has been bitter year after year. I finally fell in love, and I thought my life would be smooth sailing, but unexpectedly, I received a text message to open a room, plus a fan's "Bai Bai Bai" photo. The cuckold was placed directly on the head, and the white hair split. From that day on, he swore a vicious oath: "If you fall in love again, you will be a dog!" Unfortunately, contrary to expectations, a white-haired fairy who claimed to be his "sister" broke into Shen Bai's world. At this moment, he suddenly realized that this was the real end of all hardships! "Brother, I am really your sister. If you don't believe me, just touch me." "Brother, do you like sports cars? Can I buy them for you~" "Brother, you are not good! You are not allowed to look at other girls. You can only belong to me." … Press conference many years later. Reporter: "Mr. Shen, you are successful in everything you do. Why is that?" Shen Bai smiled lightly and hugged Jiang Jinyao, who was as beautiful as a fairy beside him. "It's very simple, just find a rich wife to keep you!"
