In the years before Muyao turned 20, her biggest life goal was how to turn her crush into a love interest. She had a crush on him for eleven years and loved him all her life.
Mu Yao: "Even if you know that the person you like is a scumbag, you will still fly into the flames without hesitation."
Sun Jiashu: "This thing is too mysterious. If I really want to say it, I just need to meet someone who makes me a better person!"
This is an eleven-year secret love, a lifelong love. They support each other and turn the imperfect him (her) into the most suitable him (her).
