Eli, a rabbit-like beastman, lives in straitened circumstances. To pay off his debts, he works various odd jobs and eventually becomes a cleaner in a high-rise building. One day, he inadvertently helps Adrian, a domineering CEO, obtain an urgent document. This accidental encounter draws the usually indifferent Adrian's attention to this quiet and gentle rabbit. The two begin to interact and their relationship gradually grows closer.
However, the huge debt Eli was burdened with weighed heavily on him. Adrian offered to pay his debts on the condition that Eli signed a contract to become his lover. With no other options, Eli had no choice but to agree and move into Adrian's luxurious world, which was vastly different from his own.
During their cohabitation, Eli gradually discovered a shocking truth - Adrian was actually the neighbor's child from his childhood. However, Adrian had actually known everything from the very beginning. From the first day they met again, Adrian had made up his mind to be with Eli. Eli thought it was just a cold transaction, but he didn't know that Adrian had been plotting this deep affection for a long time.
With a contract that binds them both and old memories that intertwine, Eli must make a choice: to trust the man who has bought his freedom, or to flee from the love that has been waiting for him for years.
