While Yuuki Rito was still feeling frustrated about the last chaotic event at the water park where he failed once again to confess to Sairenji Haruna, however, Lala Satalin Deviluke was happy because of the confession (although uncertain) she received from him.  Still determined to get them to finally confess their feelings to each other and for the romantic trio's relationship to move forward, she decides to recreate the game her younger sisters made earlier and surprise them both in an attempt to bring them together once again. However, as usual with Lala's inventions, things go a little off course and take on unexpected proportions.
