I'm super impressed at the good characters development writing and it's super natural , not over the top! I do kinda hope NSY show more affection towards YJ but then it will be against his character too much but i'm so happy with everyone characters development! it's really a light romance slice of life drama , to be honest i kinda like watching the bromance and brother complex more than the main couple XD and i just noticed Na In woo in this drama and OMG that eyes!!! he's so good in portraying the character you can feel the pain and sacrifice in his eyes. I don't know but the OST by PJH kinda annoyed me at first hahahah but Rothy song is good here. The story is good but for me i think it's kinda weak in the end.
.
Rewatch value? maybe none but i do will recommend it to my friends , It's a good light drama to watch since most of kdrama these days are quite heavy. A good drama to take a break in life once in a while.
