I dropped this drama once, thinking how plain the female lead is, and how she left her little students by themselves only to look for a wounded man. Once I picked up again I stayed for several more episodes and the story gets better. Nonetheless, there are some fillers like Jae In's sister and Jae In's ex, probably inserted in the drama to spice up the show but they're not done right. Should expand more on Tae Ha and Hyeon Jin. The chemistry is strong with some steamy kisses. And I love the real deal proposal, it sounds so grounded.
