Saikawa, Natsunagi, and Kimizuka set off on a cruise together, during which Kimizuka unexpectedly encounters a former acquaintance. It turns out that something precious is onboard the ship, something which attracts the wrong sort of attention.
Ultimately, it's the influence
of my heart's former owner...
...هذا تأثير مالكة قلبي السابقة
Letztendlich ist das der Einfluss
der Besitzerin dieses Herzes.
Al final, es la influencia
de la antigua dueña de mi corazón.
C’est l’influence
de l’ancien hôte de mon cœur.
É a influência da antiga
dona do meu coração.
