with Illidan, we got some discussions about that
very honestly, I don't know if it's supposed to be "Soleil Moi" (both french) or "Soleil More" (fr+en)
if I should choose, I'd choose the former even if both make no sense and lyrics don't help
("to iu koto" isn't a single word, so I don't see why it should be treated as such)
