I loved it soo much ... everything was soo good in this kdrama. I really really wanted Kim jojo and Sun-Oh to end up together ... was a little bit disappointed in the middle of season 2 but then as it continued I felt much better for how the story went.
it felt sad to see Kim jojo choosing Hye Yeong over Sun-Oh because after she broke up with Sun-Oh he was miserable it was like he never smiled after that which was soo sad to watch ... then when Jojo and Hye Yeong became a thing Sun-Oh and Hye Yeong's friendship broke which left Sun-Oh left alone and lonely.
But the end was good in my point of view where Sun-Oh ended up with Yuk-Jo not leaving him alone and sad ... they make a good couple.
