Mitsuki Momota, a cashier at Aozora Mart. After graduating from university, Mitsuki's ex-boyfriend introduced her to this job to thank her for the ruined relationship. At Aozora Mart, Mitsuki is the cashier, sales assistant, and cleaner. But she does all of it with no objections. Her manager, however, is someone she can't figure out. He is lowkey and doesn't talk much in front of the customer. But in the break room, he is the one you might say the most charming one.
