There's a small bit of flashback about Goriki(Joo-Heon) in this episode that connects him to Ogawara(Tae-Joon). It's only a bit but it shows enough on why he really hates the guys guts. There's quite a lot of relics introduced in this episode, will Joo-Heon get to use them? Well, let's just see the future episode on what direction will the studio take on this.
