Love will never know its depth until it is time to part.
——Gibran "The Prophet"
Lyrical version:
Xu Zixiao: If in your heart, I am no longer a good husband, a good father, or even useless, then why did you fight so hard to marry me in the first place?
Gu Yihuan: Yes, I regret it. If I had known that the result would be like this, if I was given another chance to choose, I would hide far away from you. I would never fall in love with you again, let alone marry you or give you a child.
Spoiler version:
A mother suffering from postpartum depression, a strange psychological treatment, a wonderful time travel, and a love that is not perfect.
