I think the two romantic relationships had great chemestry, but the main couple had some things that made me less excited to root for them. I hated that she took advantadge of his illness, it was a really shitty move that a good person would never do, specially a person who has a blind brother and knows how difficult life is for him. And specially a person who knows he has trust issues because somebody betrayed him and he can't even trust his family. I also didn't like the whole in love with fake Veronica and in love with the secretary, beause the way he came to the conclusion he was in love with the secretary felt forced. And I also think the forgiveness after he finds out about what she did was very rushed. I think the main couple had good chemestry, and their kisses weren't awkward, but that I wish their storyline would've been different.
Regarding the other pairing, I really loved them. Veronica Park easily stole the show, I loved how she was hurt by others but that didn't make her mean even if she pretended she was. She always tried to help and was honest and vulnerable.
I don't think I'll rewatch this drama, it wasn't bad, but it wasn't original or very special. I think the only scene it burned on my brain was how the male main character reacted to knowing his secretary lied to him, about how his illness affects him on is daily life. And how our facial expressions are part of human interactions and you can feel isolated when you can't see them anymore.
