Believing she is still wearing her swimsuit Naoto looks at her and sees her bra, flustering them both. As the rain continues Hayase invites Naoto to her home which is close compared to his long walk home. Unable to leave after Hayase puts his wet clothes in the dryer Naoto is invited to play games.
