Tamaki Tsuru enrolls in Aonagi University with the intention of experiencing a typical university life by making friends and finding a boyfriend. To achieve this, she decides to try out for the tennis club despite not being naturally athletic. Unfortunately, her attempt backfires when she accidentally damages a model glider with a tennis ball, prompting Daisuke Sorachi from the Aviation Club to demand compensation. Despite her reluctance to join the Aviation Club, its captain Jun Kuramochi employs various tactics to persuade Tamaki. He offers her opportunities to earn the money she owes while also helping her find a boyfriend. While initially hesitant, Tamaki eventually agrees to join, but soon realizes that Jun's motives for recruiting her may be more significant than he lets on.
