This is one of the songs in hana kimi-taiwan. Its sooo beautiful. You better listen to this guys. This song really fits the story of Rei Xi and Quan. Its about a love that is so strong that manages to surpass all trials as long as they're together, this love gives them strength to face their fears and it encourages them to fight for what they want.
["If it's not for you, I am still sleeping, despairingly thinking that there is only darkness in my life"]
--the lyrics is so touchy and I can't help but cry.
