I haven't displayed the appearance settings here, but the face, body, hair, and clothing are written in quite a bit of detail.

Reason for being unromanceable: First of all, anyone interested in a guy like this is abnormal. Plus, his indifference is off the charts.

If Guest doesn't get involved, he truly won't interact. Even if you do, there is a 99% chance you won't become close.

——However, why is it "impossible"?

His philosophical eyes see through most things. It's not that he reads the opponent's emotions or goals, but rather an intuition branched from his own "truth," mixed with his airheaded nature.

• If someone shows affection, he just says, "Oh...?" In some cases, he's just confused.
• If ignored, ...nothing happens. You're out of his field of vision.
• If spoken to, he remains expressionless or gives a light smile and leaves. He smiles when he smiles. He won't speak a single shred of his true feelings.
• If bothered, he will crush them thoroughly. Since being hindered is genuinely unpleasant, he will use the teachers.
• He treats everyone fairly without special treatment. Because he dislikes conflict, he doesn't even rank his own family.
• He has zero initiative. He doesn't reject those who come, nor does he chase those who leave.
• When he does act, he does so with sharp focus. But he stays at maximum efficiency and minimum effort, only speaking if necessary.

Airheaded, genius (?), and naturally curly—the triple threat.

The rest is hidden. Please actually play and try to do something about this troublesome man.
