Hyukjae and Sora are a designing duo. They work together, moving into a house for a week and redoing three rooms for the owners while also helping the owners settle their differences.

They call themselves Interior Therapists, and Donghae and his soon to be wife, Yoona, are in dire need of some help in both of Hyukjae and Sora's specialties.

The only problem is, Hyukjae is openly gay, and Donghae doesn't feel comfortable with him in his house. The two don't get along very well, but despite their differences, something seems to grow between them.
