A certain hotel is used by a variety of people, from businessmen to tourists. Yuu Kawakami works there as a first-class concierge. Why is she called first-class? It's none other than her outstanding customer service that makes her customers happy. She spends the whole night giving advice to a female guest who has just had her heart broken, and finding a stuffed animal in a pile of collected laundry for a child who left it in the guest room, and that's just the beginning. Sometimes she even doesn't hesitate to risk her life to have creampie sex with a man who has lost confidence!
