Taehyung is a 27 years old single father of his adopted daughter, who makes ends meet by his writing job.

One day, his daughter, Elina, brought a stranger-homeless-teenager boy home. Unacceptable of course, because he is very protective of his baby girl but somehow that boy ended up staying with them (and became Elina's crush). Taehyung couldn't get rid of the feeling that there's something to this boy, Jeon Jungkook than what meets the eye, something that's hidden very well underneath his surface. Can he figure it out in time? Or his curiosity will get him devoured?
