Does the love between childhood sweethearts last forever? Or is it a promise made as early as I can remember...?
"Han Han~ Teach me, teach me~"
"Why are you so crazy again?"
"Oops~"
"Hello, I am Han Su"
"Hello, Mr. Han, my name is Yan Yi."
It's not that we don't love each other anymore, we just... Haven't seen each other for a long time...
Intention: Absolute love will not be lost in time
