i somehow remember this song and posted it today.. it is a very nice song as it is composed by jay chou. there is really no formulae to a relationship, one plus one is not two. at the right time meeting the wrong person is a joke. at the wrong time meeting the right person is a regret. so is all about at the right time meeting the right person... well wad a song for valentine.. enjoy the song, cos emo can be beautiful.
