Father needed to STFU and just let them be.

Finally!

I wouldn't mind if the series ended like this, I don't want more drama. :P

Yeah even if in the end the two actually fell in love, the father is still bad.

@givemersspls yeah.. the father cares more about someone else child than his own.

Perfectly put @givemersspls

The fuck happened with the father's diet and health problems? You know, the very first thing introduced in this series?

Also, if this was his "plan" all along, to make them a couple, he is still a pretty awful father for all of the lying, manipulation, lying, backstabbing, and more lying he did to his middle-school aged son. For the purpose of setting up an arranged marriage...for a son that is highly unlikely to be able to take on such a burden, as Sang-Won himself explicitly said.

If the father was just like okay, this is nice and had no nefarious plan to do this, then that's at least better.
