Cheng Pan is a wolf dog that is difficult to tame and will even bite people when necessary, but he has an unknown secret. He loves Chi Wanyang.
No one understood why Chi Wanyang wanted to adopt him. Only Chi Wanyang thought that he was a little puppy with no offensive power. He didn't even dare to show his fangs and only dared to rub him with his nose. Even when he rubbed against him, he was careful.
Purpose: Mutual salvation
