Boy name = Mr Leo
Girl name = Mrs Jenny
// Fall in love river.
The boy love the girl;
// They love each other.
The girl loved the boy;
// AS time goes on.
The boy can not be separated the girl;
// At the same time.
The girl can not be separated the boy;
// Both wind and snow all over the sky.
// Whether on foot or 5 kilometers.
The boy very happy;
The girl is also very happy;
// Whether it is right now
// Still in the distant future.
The boy has but one dream;
// The boy wants the girl could well have been happy.
I want to say:
Baby, I would love you forever;
亲爱的，这是我们在一起走过的时光。 Love you forever!!!
