Irreplaceable.

有谁能告诉我,
当你欲哭无泪的时候,
要怎么办?

Nobody has taught me that.

When it's too messed up inside. When all I need is a simple, but sincere hug. A hug so tight that it'd keep me warm. A hug so tight it'll make me cry.

A hug so similar to that of yours... but if there ever was a similar one, it'll only render the title meaningless :)

If only they could see,
If only they could see what's inside.
