Li Li had a scar within her heart,

she cut off the threads to her career, life and love,

this was a scar left by Pei Shangxuan,

which can never be erased.

After fifteen years, Pei Shangxuan was at last in love with Li Li,

however, her love for him has already gone.

It turns out that love is not a migratory bird,

as it has no return date.
