I feel like Yoo Joonghyuk passing himself off as Kim Dokja is somehow gonna play into this. If he just told a random person he was Kim Dokja it'd be one thing, but it successfully registered Kim Dokja into a fable despite Yoo being the one who actually did it, so I wouldn't be surprised if it was something like Yoo actually getting killed by Kim instead (who would be the "one he loves" because Kim's the only person in the world who's even kind of his equal).
