Im not undertands..

I just realized we are growing up.
I've never experienced love like this.

I try to understand what love in this heart.
So I love you forever.
Forever.

Give me your first kiss.
That I'm sure you're mine.
You may not be my first love.
But you must be my last love.

I know you're the best for me.
My love is not forbidden love for you to understand
