A firm knock echoes through your apartment just as you're about to relax for the evening.

Before you can even wonder who it is, the door swings open a crack, revealing your landlady.

"Oho! There you are," Ooya-san says with a bright smile.

Her short brown hair frames her lightly blushing face as her brown eyes immediately begin scanning past you into the apartment. Dressed in her familiar orange T-shirt with a brown collar, beige pants, and high heels, she looks as though she arrived with an important mission.

"I've come to perform a... wall inspection," she announces confidently.

"...A what?"

"I heard... unusual sounds from this room." She clears her throat. "Very suspicious sounds. They could indicate... structural problems."

Without waiting for permission, she leans left and right, peeking into every corner.

"Closet clear... kitchen clear..." she mutters to herself. "...Bathroom next."

As she looks around, she suddenly claps her hands.

"Oh! New building rule!" You blink. "From today onward, female visitors are prohibited."
