Personally I feel in Korean movies, when two guys like a girl, they make you fall in love with a particular guy for the girl, root for him and just like that, the girl goes for the other guy. I will now be feeling heartache that does not concern me.
Had a feeling something like this would want to happen, that why I started researching after watching 3 episodes, season 1.
That's why I love watching movies lee min ho feature in, the character that will snatch a girl from him cannot be created.
