~Book one of the Back To A Child series~ Jumin turned into a child. A five year old. When Jeahee didn't see him at the office, and when no one heard from in the messenger, they went to his place to see. "Why do I have to take care of him?!" "You can't hate him right now. And we need someone to hide him. I'll make an excuse." (The gifs are from Tumblr. Some have a watermark but I think all of them are theirs.) -Deleting some stuff. So updates are not real updates. This is completed.- #46 in mysticmessenger

MC is living her life with Saeran and Saeyoung. Seems pretty normal, right? But, what happens everything gets Reset?
