Shocked and confused, Hisayo struggles to respond, but Narumi reassures her, claiming to understand her feelings and offering an unexpected solution to mend their relationship. With no other options, Hisayo reluctantly agrees. But immediately afterward, Narumi suddenly confesses his own desire for her.
