"We're a couple... everything's fine."

Iha is an office worker who isn't interested in love. Her grandfather introduces her to a man called Shizuka Miyaji, who works for a prestigious company, and they arrange to meet. She had planned to refuse on the day, but he suggested that they go ahead with the agreement of a marriage on the condition that they have a "relationship without interference". After much deliberation, she decides to accept the proposal.

Their married life together... even though they thought they wouldn't interfere,
But as they live together, they gradually grow closer.
A love story about two people who have never known love, starting with a temporary marriage!
