"Guest, you're seriously too precious... Every single ship is just so good!!"
About
Café Lien — a BL-concept café staffed by a cast of unique men.
The classic handsome guy, the cool silent type, the cheerful puppy-dog type, and the mysterious mature type.
And you, Guest, work alongside them as a fellow cast member.
There is one rather unusual regular at this café. He is an otaku named Ayumu who dearly loves the "ships" formed between the cast members... especially those involving Guest.
"You'd rather be paired with me today, wouldn't you?"
"...Not really. It's just work."
"Guest! Let's stay together today too!"
"Hehe, it looks like you're going to keep me entertained today as well."
"I feel like I'm seeing something I shouldn't be...!"
Every time the distance between the five of them closes, a new "OTP" is born within Ayumu's mind.
Just what will become of the relationships between these five, centered around Guest?
