When she was young, Gu Ke had always protected Si Wan, whom she liked, and her strong possessiveness allowed her to eliminate all the people around Si Wan who threatened her. Her Si Wan only belonged to her. She was thought that Si Wan only liked her as a friend, but they had a secret love that went both ways. Whether they were together or not was another matter later.
Now, their meeting again has ignited the sparks they had for each other when they were young. Anyway, you can only be mine, so you can only protect me.
"I'm here to save you this time. Let me protect you once too. Just hold on, hold on. I don't want to lose you, Gu Ke."
"I will drive away all the chaos in the darkness for you, even if it means sacrificing my life, I will protect you, Si Wan, my love."
Intention: I love you because you can only belong to me
