She locked him three times.
The first time he was locked at the ankle, he broke his hairpin and climbed over the wall to escape. She sat on the locust tree outside the wall and waited. She lowered her head and blew into his bloody palm: "For the first time, I forgive you."
The second time it was locked in his heart, he had already pried open the lock cylinder but walked back to the cell, while she stood outside the door and said to him through the door panel: "Xie Qingci is getting married."
The third time he took the initiative to put on the chains and put his life in her hands and bet that she would believe him. She held the bloody drawing for three days, rushed into the dungeon and knelt in front of him: "I'm sorry."
Later, he untied all the chains, stood in front of her and said, "Let me go. I'm afraid I won't stay any longer, so I can't bear to leave."
She lets him go. There was a strong wind on the tower. She held the old chain he left in her palm, with a line of words engraved on the inside -
"I ran three times and you chased me three times. The fourth time, I came back to find you."
