Sweet and Flirty! Brother and Brother Are Addicted to Pampering Each Other

[Age difference + straight crush + sweet pet + mutual redemption] Note: The male protagonist is gentle in the early stage (pretend), but becomes more sinister in the later stage (a bit yandere at heart) Shen Xingyue has a secret that has been hidden for many years. She has liked a person's voice for five years, and she even wanted to blaspheme the owner of the voice many times in her dreams. Even though she never knew what the owner of this voice looked like. The first time I heard this sound was one night in the third grade of junior high school. She came home from evening study and overheard her brother calling. That voice was like the warm sunshine in winter, sweeping away the worries in her heart. But she hadn't heard anything since. The next time I heard it was in the game room five years later. He was the friend that her brother brought her to play games. "Kid, I am your brother's brother, my name is Xiao Lingfeng." This time his voice changed a lot compared to last time, but Shen Xingyue still recognized his voice just by relying on these words. It no longer had the wanton publicity before, and became low-pitched, cold and a little gentle, but it sounded as good as ever. , It was obviously a voice that I had missed for a long time, but Shen Xingyue felt timid when I heard it again. He opened his mouth for a long time before finding his voice: "Hello, I'm Shen Xingyue." This sentence used up all her courage, and she dared not say another word. ... Xiao Lingfeng has been the envy of others since she was a child. But they don't know that home is a luxury for him. He has never felt maternal love, and he has no idea what a loving home is like. Even if he later grew up and became the president of a company, it was a pain that he could not erase. (The introduction is too weak, please move to the text)
