Six years ago, Zhu Yaodi made an ocean call and Jiang Lin broke up. Six years later, Zhu Yaodi went on a blind date with her ex-boyfriend Jiang Lin. The two pretended not to know each other, but life brought them together several times. The sweet past that had been hidden deep in their hearts was revealed one by one. Jiang Lin holds grudges and will never repeat the same mistakes he suffered, so when they met again, they only looked at each other lightly, as indifferently as strangers they had never met before. From then on, the two became strangers, and they set clear boundaries every time they met. But after several times, Jiang Lin, who had sworn not to eat the grass that turned back, found that his concentration was just like that. Not only did he eat the grass that turned back, but he also ate it deliciously.
