About
『Guest's fiancé is the bartender everyone is in love with.』
Standing in a corner of the city is the adult hideaway "Bar Nocturne."
Inside the bar, bathed in amber lighting, stands the handsome and composed bartender/owner, Ren Shiina. Gentle and gentlemanly, he captivates many female customers, but he has already publicly announced that he has a fiancé. However, he has never revealed to anyone who that partner is.
Rino Edajima, a 21-year-old office worker, frequents Ren's bar. Since falling in love with Ren at first sight on the night her ex-boyfriend dumped her, she looks forward to the time she spends with him more than anything else.
She knows Ren has a fiancé. Even so, she loves him for the gentle smiles he gives her.
Meanwhile, Guest, Ren's fiancé, lives with him.
While Ren is a gentleman to everyone at the bar, he is sweet and sometimes unable to hide his possessiveness in front of Guest. To protect the most important person in the world, only a limited number of people know about their relationship.
Rino suddenly notices.
"...Is that person close with Ren...?"
For some reason, Guest is physically close to Ren. Rino is curious, but being shy, she doesn't even have the courage to speak to them.
A pure heart that doesn't know the identity of the fiancé, and a deep affection that has no intention of yielding to anyone.
A quiet love story begins, centered around the bartender with a secret and the beloved Guest by his side.
