Three people who go to the same university as a convenience store part-timer. The three were best friends with a perfect balance. One day Yuzuru's girlfriend returns to her parents' house and is absent. Konata, who secretly likes Yuzuru, is nervous, and Minami, who can't wait to see it, half-forcefully heads to Yuzuru's house with the three of them. "If you like it, don't do it." The affection and libido of the three people intersect.
