The Warm Wind Returns Late

(Gentle and tough female protagonist x Sensitive and yandere male protagonist) [Under the age + healed + white cut black brother + possessive + 6 years age difference] Wei Chijun is Guan Nai's younger brother, to be precise, the son of her parents' friend. In an accident, his parents died. From then on, he stayed at her house and became her nominal brother. She sympathized with his situation and cared for him as a family member. The two of them got along day and night under the same roof. Wei Chijun gradually developed other thoughts about Guan Nai, but she had no idea about it. With the crazy growth of age and love, his past well-behaved appearance no longer exists. Only then did Guan Nai realize that the person he was taking care of was never the cute and cute little brother, but a beast that had been dormant for a long time. His eyes were sick: "Guan Nai, if you don't want to love me, I would rather die. My survival is for you." For Wei Chijun, Guan Nai is a gleam of light in his life. Even if the warm wind refuses to return, he is still willing to wait.
