Original caption
Here is a natural and novel-style English translation: 🐺 A strong and cold-hearted Alpha, he reserved every ounce of his gentleness for his younger brother, who wasn't related to him by blood. From the day their mother brought home the newborn baby, he made a silent promise to protect him for the rest of his life. 🍼 As a child, his little brother was always toddling after him, calling out, "Big Brother... wait for me!" No matter where he went or what he did, the only person in the boy's eyes was the older brother he loved, admired, and trusted more than anyone else. 💙
