The Mute Brother [Reborn Twice]

Fang Zhiyi had hated the mute boy his family took in ever since he was little. The mute boy couldn't speak, but everyone cared about him. He took Fang Zhiyi's snacks and affection, and Fang Zhiyi even had to call him "Big Brother." Who would want such an annoying big brother! That was what Fang Zhiyi had always thought. Until the mute boy stood in front of him and took a dagger to the heart. When Fang Zhiyi woke up, he had been reborn at six years old. That was the year the mute boy first came to live with his family. The other children in their courtyard had ostracized him, and he was covered in mud. Fang Zhiyi immediately charged forward like a ruffled chick and stood in front of him: "Who dares bully my big brother!" - Everyone knew that Fang Zhiyi and his mute big brother had been closer than anyone since they were kids. They went to school together, ate together, slept together. If anyone dared say a single bad word about his big brother, Fang Zhiyi would fly into a rage. Fang Zhiyi, too, thought he and his big brother would always be this close. Until he saw his big brother, now in college, being held affectionately by someone else, a man. Fang Zhiyi's rebellious phase had finally arrived. He wanted to drink. He wanted to be bad. He ran to a tattoo shop, wanting a blue dragon on his left arm and a white tiger on his right, but his big brother, who had searched ten streets for him, dragged him home with a dark expression. "Stop controlling me!" He kicked and struggled. "You're not even my real brother!" As soon as the words left his mouth, he saw his big brother's bloodshot eyes, as if he hadn't slept in ages. The light in them went out instantly, as if Fang Zhiyi had stabbed straight through his heart. Fang Zhiyi's heart ached, and he blurted out, "If you were my real brother, how could I still be in love with you..." Big Brother: "...?" Fang Zhiyi: "..." Oh no. Could he take that back? - Of course he couldn't. So later, all he could do was let his big brother hold him by the ankles and grip his waist while he sobbed and begged for mercy, barely able to catch his breath. Eight-year-old Chen Chao was forced to live under someone else's roof, and the child in his foster family hated him. He didn't like the spoiled little brat either. But he was the big brother, so he wouldn't stoop to arguing with a kid. Until he gradually began remembering the knife that had stabbed him in his previous life. And the boy who used to cry whenever he fell now kept saying he would protect him. His arms were so thin they looked like they would snap with a twist. Who was protecting whom, anyway? Chen Chao kept a cold expression as he warmed milk for the spoiled brat, cut up fruit, and did his laundry. Finally, he hauled him out of bed and carried him to the sink to brush his teeth and wash his face. He could spoil him if he wanted. Spending a whole lifetime like this didn't seem so bad. 1. Childhood sweethearts both reborn, a cozy slice-of-life story. The first part is when they're little; they grow up around the time the story goes premium. The whole novel shouldn't be very long. 2. A talkative, tsundere, easy-to-placate silly bottom * a cold-faced, devoted top from a terrible family. (A younger brother who is obsessed with his big brother but denies it, and an older brother who's obviously obsessed with his little brother.) 3. The top can't speak because of a psychological problem. He'll recover later, probably near the end. Theme: Face hardships together, and the future will be bright
