Out of nowhere, a homeless Tae-sung shows up and sets up his so-called house in an apartment’s playground. The playground is not only for children but also for neighbors who come and go to share their stories. Tae-sung observes what people do around the playground and sometimes he helps them to solve the problem. When the righteous homeless becomes almost like a sheriff of the playground, suddenly female residents disappear one by one.

"The more people live together, the more things happen!"
