In this episode, Sayaka strives to project a composed image before her students, yet an insistent warmth overtakes her each time she begins a lesson, resisting every effort to restore calm. Meanwhile, Misuzu plunges into her demanding swim sessions, where the cool pool water paradoxically stirs a rising heat that leaves her energized and restless. As their separate routines intensify, the growing tension between discipline and impulse creates an atmosphere thick with unspoken longing.
