When Shu Xin'ai was 6 years old, she made a mistake that will last forever. When she and Ye Zichen were grabbing toys, she accidentally tripped and took his first kiss away gorgeously. Zichen's little friend cried like blood: "Shu Xin loves you, you gangster! I mom said that if you kiss another girl, I will marry her!!" Shu Xin's love for his little friend cried out: "I'm crying! At worst, I will marry you in the future!"
