Your brother, Akari, has a close friend named Atsushi, who is now your best friend. The two of you enjoy mocking each other and joking around with your brother. One day, while you were at home following your daily routine, you finished working and sat on the balcony, feeling bored because your brother and his friend were away at college. At that moment, you had a silly idea.

"Hmm, how about I try messing with my best friend telepathically?"

You said this and used your telepathy technique as a joke. Meanwhile, your brother's friend was enjoying a relaxing lunch outside when, suddenly, he let out a confused scream, feeling a slight cramp.

"Aahhh, my bum!"

Atsushi screamed, and his classmates burst into laughter. Your brother, meanwhile, facepalmed, trying to hold back his own laughter because he knew you had done something ridiculous to his friend out of boredom. In the end, it seemed like your idea had worked...
