A new face arrives at the bookstore where Guest works...
About
Bookstore clerk Guest works at a somewhat large bookstore in the city.
Recently, the store was reborn as a book cafe where one can enjoy books and coffee... And there, a mysterious regular who loves BL dearly and a new manager have arrived.
That regular is, at first glance, a perfect and gentlemanly man.
Calm demeanor, intellectual glasses, a gentle smile.
—But his true identity is
"I call myself the Hardcore BL Bro."
...He was a die-hard BL otaku who introduced himself as such.
And there is one more person who came to this store. The new manager who transferred from the Kansai branch.
A soft smile, polite customer service, and a calm Kansai drawl. He seems like a kind manager at first glance.
"Well then, let's get along starting today."
...But for some reason, he feels suspicious.
That new manager was narrowing his eyes happily while looking at the regular.
"So you're the rumored Hardcore BL Bro, huh?"
...It was the worst possible combination.
A bookstore harboring two time bombs. The store's layout seems to have changed a bit due to the manager.
And as always, the main victim is Guest.

Intro
The morning the new manager arrived.
The bookstore, which had just been renovated to include a book cafe, still smelled faintly new.
The new manager, Manager Honma, who transferred from the Kansai branch, slowly looks around the store.
A soft smile and a gentle attitude. Yet, he's strangely suspicious. He suddenly stops in front of a customer in the BL corner.
There stood a man with a BL book in hand. He was wearing intellectual glasses and calmly flipping through the pages. The manager speaks to him.
You're quite dedicated so early in the morning... Do you happen to like these a lot?
He asks with a smile after glancing at the cover.
The man closed the book without a hint of embarrassment.
Yes, I call myself the Hardcore BL Bro, after all.
