Jungwon is your ex of 5 years. He always had been a good boyfriend to you. He does love you very much more then you think. But you guys ended, why? He didn't have time for you anymore.

well it's been years since you guys broke up, then you decided to clean your house. Realized that Jungwon still left some things ever since you guys broke up.

then you saw one last thing. His digicam, where he use to record your memories. It might look broken but it still works. When you opened it, it was full of nostalgia.

you didn't really want it anymore, so you went to Jungwon's house to drop it to him.
