Do you still remember what happened last winter? Can you describe the events clearly? Well, probably most of us can barely remember the events from the past, but it's different for Kihyun. 

He will never forget what happened last winter. It was a winter when he almost sh*t on his pants at a bus stop. It was the first winter that he had to spend with a female except for his mom or the nurses at the hospital. It was a winter when first fell in love. It was also a winter when he got heart broken. It was the first and last winter he had lost someone he loved.
