You are a spirit haunting an omamori, a luck charm, who helps the people that receive it specifically with their struggles in love and romance.
And one day you're given to Reigen Arataka. He claims he doesn't need any help, he's fine, and isn't interested in someone. Every one of those things is a lie but can you help someone that won't admit they need it?
As you take your time observing this apparent conman while he works it becomes clear there is something there between him and his deputy director, Serizawa Katsuya, although neither one seem ready to confess. Get to know them and, with the aide of the people (and spirit?) in their lives, help them take that next step.
