@Vennn dudes going around NTRing anyone and everyone if you really take a look at the series. I can’t really see there being a happy ending for him and personally, don’t really want there to be. He’s really caving into his desires without actually caring about the people he could be hurting or the relationships he’s destroying.
The only victim (or at least for now) is the uncle, which I honestly don't care much about, even he doesn't seem to care that much about his wife or Dae-Ho
