Girl, there is an angel living in your heart. When she met him, her pure blue wings slipped down and turned into love... In the chaos, she suddenly realized that he might have been nostalgic, but after all, her heart only held an "unforgettable heart", and what was left was just the blue silhouette of the past; and he passed by her, but he had been silently her guardian angel. ——Girl, would you rather be a shadow with a heart or an angel without a heart? [Character] Lin Ruoer: Blue should be pure, just like love cannot tolerate impurities. Shen Xuanye: ... What if I say I really love you? Bei Chenyi: Even if your heart is gone, you are still my angel... Qiu Nuo: How could I not come back, knowing you are waiting for me! Qiu Yang: In my eyes, you are always just you. Lingfei: My love is my own business and has nothing to do with you! Yuan Yiran: Are you afraid of falling in love with me if you don't dare to try? Ai Yanqing: I think I will never fall in love with you.
