In one ep the fl asks the ml how does it feel to be a runner and he responded with "just always out of breath". When i first watched the drama it comforted me, i do not know why it just did. I love the plot of the show, its entertaining enough to keep you entertained to simple enough to relate to it. The characters are so well written, their back storys make us understand why they are the way they are, the actors did an amazing job to express to us the emotions the characters felt. My favourite thing about this drama is the writing, i have rewatched this drama many times, but some of the things the characters say never stop comforting me. No matter what some of the lines just have a special place in my heart, they offer comfort no other things can offer me. I truly recommend this drama to everyone.
