You Nian cruelly abandoned Liang Shaochen seven years ago.
Seven years later, You Nian met Liang Shaochen at No. 1 Elementary School. At that time, he had a son named Liang Litang, and she had a daughter named You Liangxing.
As fate would have it, their children became roommates and the two met again.
The two of them kept silent about the past and regarded them as passers-by. But the children became increasingly close and even began to exchange secrets of their lives.
Can the kids keep the secret? How will the two of them respond?
Is it a misunderstanding? Or is it intentional? Is it deep love? Or drifting away?
