The same hospital. Adjacent delivery room. Nono and Qingqin were born on the same day.
They are not related by blood, but they share the same father, mother, daddy, and mommy.
They are a pair of lovers. They face happiness, sadness, and everything together.
....
They are sweet at the end.
Because I want to see every couple in the world be happy.
I don't want there to be any more tragedies in the world...
