Don't Bite, You Little Dog—I'm Your Brother

My name is Qi Lishen, the adopted son of the Qi family. My adoptive parents' biological son, Qi Ye, went missing when he was five years old—fifteen years ago now. On their deathbeds, they kept telling me I had to find him. But when I finally did, he had already become a fool. I thought I was bringing home a poor, pitiful pup. I didn't expect a wild dog—not only food-aggressive, but baring his teeth. When I tell him to call me brother, he opens his mouth and barks. No choice—shut the door and slowly train him. But why—hey! This dog keeps climbing on top of me looking for candy! I'm the CEO of the Qi Corporation, and I'm fighting wits every day with a 1.9-meter-tall dumb dog. Wait. Is something off here? Clearly I was the one taming the dog, so why does it feel like I'm the one being tamed?
