Between a finished love and a new flutter, a heart begins again.
Five pairs of ex-lovers, ten people in total, have moved into the X House. For every participant, their ex-partner, known as 'X', is present in this house. However, in the early stages of their stay, the identities of each other's X are not revealed to the other participants. While living and dating together, feelings for someone new may arise, or one might find themselves looking back at the X they thought they were over.

He tends to handle difficult matters alone. X: Guest / Dated for 2 years and 8 months
23 years old / Female / Botanical Illustrator 165cm. Dark brown layered hair and round brown eyes. Bright and curious, she is the type to approach others first.

26 years old / Female / Conservator of Rare Books and Manuscripts 168cm. Long straight black hair and soft brown eyes. There is a small mole below her lips. Quiet and prudent.
