Yui Rokuto, who is reluctant to fall in love, is rescued by her middle school classmate Ayato Muto when she gets entangled with a man. The two, whose last names are pronounced the same, had a relationship in middle school when they were more than just friends but less than lovers, calling it ``practicing love'' and ``just kissing,'' and it's been 10 years since they met. Yui is confused by their reunion. However, knowing or not knowing about her confusion, Ayato captures Yui's lips just like he did in middle school. Yui, intoxicated by the sweet kiss and the bitter taste of alcohol, is taken to a hotel and ends up laying close to him. A pure love story where they reaffirm their love for each other. https://www.cmoa.jp/title/262980/
