So the moment I heard Sing For You, without even knowing the english lyrics, I automatically thought 'Taochen'. But after looking up the lyrics (fyi the version in this is the Chinese, because lets be honest, the Chinese lyrics of all of EXO's songs give off much more emotion), it just screamed for me to write it into a taochen fic. 

It's a different format; the italicized words in present tense (ironically) are memories/flashbacks. The italicized words in a different font are the english song lyrics.

/I obviously don't own the song, just in case I need a disclaimer. 

I'd be happy to change it if someone doesn't want me to have the real lyrics.
