I think this drama is targeted towards female audience. The relationship between the ML and FL is kinda toxic. Sometimes, I feel bad for the ML. VERY TOXIC RELATIONSHIP. I know that FL had problems expressing her feelings but from ML point of view, i feel bad for him(he is literally begging for love). FL had deep feeling for secondary ML that somtimes she switches her heart even after she got together with ML even after her promise with ML. I feel like FL lacks feelings compared to ML.
