Plot
After high school, lovebirds Yuu and Saki thought they had the rest of their lives planned out with them heading to the same college, but unfortunately for Yuu, he flunked his entrance exam!
Stuck studying for mock exams, Yuu forces himself to focus and buckle down, in an attempt to ignore the touch and whispers of a neglected and antsy Saki who's starting to lose her cool. She hears that sexual arousal supposedly helps activate brain activity and with hours of studying not working, she's going to spend all night stimulating his brain power!
