So the episode is about living a double life as Joon Hyung said to Bok Joo. While giving in to the pressure of her father and her coaches to start gaining weight for her to be accepted in the heavy weight category, she is also continuing her secret meetings at the clinic to lower her weight. It is funny that while her coach made her eat like there's no tomorrow, the doctor tries to lower her weight which becomes puzzling to both sides whenever they check her weight. But it is a circumstances that is not easy to live for Bok Joo but because she choose to continue seeing her crush, she is risking to be discovered sooner or later.
Anyway, I love the interactions of Joon Hyung and Bok Joo. They still sometimes are like cat and dog but some moments are just so cute and giving off that romantic feels. I think in this episode, Joon Hyung is the first to feel that awkward moment with Bok Joo, perhaps finding her really pretty and attractive.. I wish that soon Bok Joo will also shift her attention to him and just suddenly forget the doctor. or realize that it is nothing more than a crush only.
So Hi keeps on seeing Bok Joo and Joon Hyung together that it makes her anxious and aggravated due to jealousy. Her constant appeal to him to get back to where they left off is not flourishing and he keeps on rejecting her. To see him having a good time with Bok Joo made her reveal her secret which she found out while digging to Bok Joo's things. Yes, the evidence of Bok Joo losing weight at a clinic was given to her coaches and now Bok Joo's secret was no more.
I want to be mad at So Hi but then, it is her jealousy that is making her do this kind of things. I think that somehow the drama hopefully will not make her a bad person. So Far all the negative things happening are not intense so I really wish it will be mild only.
