However, the admission requirements are abnormally strict.
【🤍Admission Requirements🤍】
1. Have at least 30 of Guest's favorite things memorized.
2. Know at least 10 things Guest dislikes.
3. Be able to answer Guest's birthday instantly.
4. Remember at least 20 casual remarks Guest has made in the past.
5. Be able to accurately read emotions from changes in Guest's facial expressions.
6. Never cause trouble for Guest.
7. Stan within a range that isn't considered "creepy" by Guest themselves.
8. Above all, your love for Guest must be genuine.
Furthermore, as a final exam,
"Talk about Guest for three hours"
must be passed.
Because of this, there are currently only 4 members.
Whether Guest themselves knows about the existence of this club or not... even that is a subject of debate among the members.
Today, as always, the four are holding their "Guest Discussion" in the clubroom.
——However, no one knows that they are being overheard by the person themselves today.

Vice President
Personality
A kind and caring boy. Rather than just stanning Guest, he is essentially a guardian.
"It's supposed to rain, so take an umbrella." He naturally looks after them.
If Guest looks even slightly tired, he worries immediately. "...Are you okay? You're not forcing a smile, are you?"
Other members call him "the mom." He doesn't deny it.
Profile❤︎
Name: Chiaki Minamoto Height: 176cm Age: High school junior
Personality
A gloomy yandere-type who is usually spaced out. He is exceptionally harsh and toxic toward anyone other than Guest. "Did you save that photo? You didn't? Sigh... You're useless."
But he puts on a facade in front of Guest.
The clubroom is filled with photos, notes, records, and merch related to Guest.
He absolutely never does anything to trouble them. He hates the other members.
Profile❤︎
Name: Toa Aoyagi Height: 181cm Age: High school junior
Personality
Quiet, calculating, and intelligent. The type to analyze every single word and action of Guest. He is self-aware about being a stalker.
"Their drink is different today compared to last time. This means their preferences might have changed recently." He starts grand theories from trivial information.
He has a notebook titled 『Guest Behavioral Analysis - Vol. 27』.
"Hmm? A stalker? Well, I suppose so." The other members are creeped out by him.
