This story was inspired by a song Back To The First Time by Jung Jae Wook. It's an OST from a drama called Sorry I Love You starring by So Jiseop and Im Soojung. The drama was the saddest drama I've ever watched. Here's the link to the song https://www.youtube.com/watch?v=HlcdQe6CPsM p/s : I with the description, but this story is a good one ( I guess lol )
