So today, I won't make an effort again. Sasami-chan is a recluse. Today, she is sitting in front of her computer, motionless, keeping an eye on her brother, who is a slave to his own dislike of effort. Through the "Brother Monitoring Tool," the outside world reveals a love comedy unfolding with three beautiful sisters and her brother, or mysterious phenomena occurring...?! This is the first volume of a 'non'-ordinary (?) love comedy that Sasami gets caught up in!
