This is a complicated yet innocent love story that started from a reunion!!! Soetani Udzuki, whose pet theory is that “All handsome men have a hidden dark side”, is a contract worker who lives a modest yet peaceful life with her pet cat, Jujumaru. Recently, to better protect her life with Jujumaru, Udzuki accepted her company’s offer to make her a permanent employee. But the workload turned out to be harder than she imagined and one day, Jujumaru even fell sick. When she had to choose between her job and her cat, that’s when the man next door called out to her. He turned out to be Yamada Aki, the man she couldn’t forget even if she wanted to. Since then, Aki has constantly tried to concern himself with her but Udzuki has sworn to herself to not involve herself with him…
