The opening theme song of the TV series "Where is the winter warm and the summer is cool" is "Once" sung by Chen Xiaodong, and the ending song is "Write You into My Love Song" sung by Chen Xiaodong.

The play is adapted from Gu Xijue's novel of the same name. It tells the story of Jian Anjie finally opening her heart and falling in love with Xi Xichen after her hard pursuit. There seemed to be a Milky Way between Xi Jichen and Jian Anjie. Every time Xi Jichen took a step closer, Jian Anjie, who was feeling hurt, deliberately took two steps back. The kind of entanglement and loneliness of wanting to love but not being able to love is really heartbreaking in Xi Jichen's eyes. Just one thing is enough to capture the hearts of the audience. The scene that left the deepest impression on me: Xi Jichen stood alone under the light, his eyes filled with despair but also with the light of hope. That light of love shines deep into the hearts of the audience.
