Lots of teasing future developments in this series.
We've had Bomi's wealthy background being hinted at for a while. This chapter actually made me think that she might be a villainess in the end, but I think she was just pissed at Hobin's boasting. She seems to genuinely like him. Why she's hiding her wealth is beyond me, though.
Now, we have a hint that Taehoon knows Hobin's father. Watch for Hobin's intrinsic talent for fighting being taken after his father, who must have been some bigshot in MMA or something.
Now I wonder who chicken-head is. Either Logan Gracie or Hobin's father, though evidence suggests the former.
