Hae-Jun left home, and Eun-Yeong is a troublemaker with no home who has been sleeping in a tent. After a bad-luck first meeting, the two have no other option but to move into an old, deserted dormitory together, and neither one is happy about it. They can't stand the building, and they can't stand each other. Across eight short episodes, the comedy, drama and slice-of-life series, with a supernatural touch, traces the hard, uneven process of two mismatched young people growing up while stuck under the same roof.
