After a year of marriage, Gu Baibai realizes her husband knows far too much about all her habits.
An accident sends her back seven years. There, she meets him at twenty-five: lonely and silent, carrying the weight of the whole world on his own. She decides to spoil him rotten.
Feeding cats, watching the sunrise, whispering cheesy pickup lines... Just when things are sweetest, she suddenly disappears.
He waits seven years. She forgets seven years.
Years later, he uses seven years of devotion to marry her all over again.
At last, she understands: he wasn't born knowing how to dote on someone. She had simply taught him how to love long ago.
