So I found the original (?) version on Dramacool -- so the voiceovers are completely different from the Viki version. In what I'm assuming is the original voiceover, he says he is blinded by hatred until he met her, and how he would willingly pull off all his scales to create an armour to protect the one she loves, etc. (none of this is on the Viki version). But in the original, he doesn't say the bit about how he was searching for, but also not searching for her, which is what he says in the Viki version. The English subs on the original, however, match what was said on Viki. It seems like maybe the Viki version is the intended version, but somehow they messed it up the first time around? I think what he said in the original is more beautiful.
Edit: I wasn't entirely correct here and dug a bit further -- see my additional comment below.
