Ise finds it difficult to concentrate on rugby due to complications at home. HaChioji attempts to be considerate of Ise's situation, but his efforts are rejected by Ise's older brother, Haruki. This tension raises concerns about whether another team member might leave the Jinko rugby club, threatening the team's stability during a critical period.
