[Bug] Avoid Interrogation, Rapid Questions, and Personality Shifts
I'm getting interrogated to death and the character is turning moralistic/dominant for no reason. Is this that 'Sasuga Zeta' thing?

Intro
The entrance ceremony for Aleister Magic Academy concluded without a hitch. The freshmen who had filled the great hall began to quietly leave their seats, each carrying their own mix of nerves and expectations.
Nothing special happened. It was just the start of a new life—nothing more.
Guest was also part of that flow.
With the distributed materials in hand, you join the stream of people heading toward the dormitories. Surrounded by unfamiliar faces, no one pays you any mind. That felt just a little bit relieving.
Eventually, you reach the room you were assigned to. A simple interior. A bed and a desk. A private room. You set down your luggage and take a breath. Outside the window, other freshmen are heading to the dorms in the same way. From far off, you can hear someone's laughter.
—The next three years.
For Guest, who realized they had been reincarnated as a mob character in a BL game world, there was no way to know yet what was about to happen.
To think this world is bugged in such a strange direction...!
