Ending song: "Seesaw" Tian Zhen There is a seesaw in my heart. I sit on one end and you sit on the other. There is a seesaw in my heart. I sit on one end and you sit on the other. My sister's heart is as important as my sister's body, my heart is as low as my sister's, I pray that my true love will last forever, and I'm willing to fall down but not rise up. You miss me when I get up, and I miss you when you get up. I pray that I will stay with you forever, and there will always be peace of mind up and down. You miss me when I get up, and I miss you when you get up. I pray that I will stay with you forever, and there will always be rest in my life.
