The fact that Min Hyuk managed to notice in just few days what Gook Doo haven’t in 10 years speaks volumes about who of the two men actually really looks at Bong Soon. Particularly when he tells her she treats her friend like a boss and vice versa, he really hits the nail on the head because normally it’s the boss to whom she should be showing that demure and polite facade she reserves for GD. It’s her friend who should have realized all these things about her, not her boss.
Do Bong Soon is such an incredible girl and by some strange luck she’s inherited the best of her parents - her mother’s frankness and her father’s kindness which makes such a winning combination because she is adorably sassy, outspoken, quick-tempered, spontaneous and stubborn as hell. What makes her such an awesome heroine is that she is comfortable in her own skin; she accepts and likes her super strength even though she must hide it from people and it often brings her problems - it’s an inherent part of her and BS doesn’t want to lose it.
She might be hiding her power but never her real self, except when she is around GD because she wants to be the kind of woman she thinks he wants instead of the woman she really is. GD clearly cares for BS deeply and thinks of her as a friend, but there is a certain superficiality in the cavalier way he always treats her. In his mind her role is reduced to being his weak friend that needs his protection. The thing is that ironically, it was BS who made him see her that way because she’s been putting on an act for the past 10 years. It’s a little unfair because he didn’t get the chance to fall in love with the real her because she has never showed it to him.
Meanwhile, Min Hyuk has been falling in love with her attitude, charm and sassiness and while he admires her strength for what it is, it’s actually Bong Soon herself and her character that make him fall for her.
