A scratch accident in a parking lot left Su Jin owing Lin Xue a huge amount of maintenance fees. In order to solve the debt and housing crisis, Su Jin accepted Lin Xue's double contract of "renting to pay debts" and "acting as a homosexual", and moved into Lin Xue's minimalist apartment in black and gray style.
From then on, the strict and self-disciplined Director Bingshan and the casual Rainbow Candy girl started a hilarious cohabitation life under the same roof. From the fierce collision of living habits (the battle between morning people and night owls, the kitchen battle between healthy light meals and rainbow cuisine), to the "acting" run-in when they are forced to cooperate to deal with external doubts (responding to provocations from parents who urge marriage and business rivals), the two gradually peel off the labels amidst countless hilarious conflicts and misunderstandings, and get a glimpse of each other's unknown softness.
As the contract deadline approaches, they discover that the pretense that started out as profit has quietly turned into sincerity through the daily ginger tea and good night lights, late-night sharing of inspiration, and the company of vulnerable moments. This is the mutual warmth of two lonely souls, the perfect complementation of reason and sensibility, and a journey of growth about breaking prejudice and bravely pursuing the true self.
