I never watched this drama but this was very nice. I'm kinda guessing that the girl is someone that resembles someone he knew or that she lost her memory. Just 100 words and the story can make you try to think 10 different scenarios lol.
Merry Christmas! OMG Thank you for this story! Read it soon as I woke up but I had to get ready to go out so I couldn't reply quickly. Anyway that was adorable! They got lost and Sae Li lost her chance for fame but it was worth it right? Spending the time with KIM WOO BIN instead! XD Thank You!!
