In my opinion the greatest drama ever

Kim hye-yoon represents in this drama in a magnificent way emotions as: love, sadness, depression, joy, guilty, anger. This serie has a perfect balance between so many genres as romance, comedy, thriller, friendship drama, highscool, adult era. If you ate eatching for the first tine the plot is really unpredictable and the story has a great message to give to the audience.
The OST is so beautiful I have some of the songs still on repat. And manily i love the chemistry between the main leads it is incredibly 💗
