One thing I don't think some people get about Jung is, he is naturally reserved and thoughtful and overall quite similar to Seol. But his father didn't allow him to showhis natural anger, possessiveness, upset, even though they were totally within normal and expected human behaviour. Jung always had to give in and be the better person and not fight back, and this is what leads him to be manipulative and showhis anger and aggression through backhanded means.
Jungs father put immense pressure on Jung, and he did it for Jung himself (as we later see, he didnt really care about Inho and Inha all that much when it was them v Jung). I think he wanted Jung to grow up well and have real friendships and relationships with people. But its impossible to have a real friendship if you have to constantly hide your feelings and only project a perfect image.
Its a shame we never see Jungs dad with his mum or Seol and what he thinks of those relationships.
Jiheon is already in love and doesn't even realise it yet, so funny
I really didnt like the prosecuter and I was hoping the white haired ML was the father from the start... but I got used to the idea that the brown haired would be the bio dad while white hair would be the partner and bonus dad and ended up preferring that. Oh well, still fun and cute! Looking forward to seeing the second couple resolved.
