10

Yuuhi pretends to be sick so Jun'ichi stays home to care for her, leading to a requested redo of their first kiss and a mutual confession of true feelings. Back at school, friends urge Yuuhi to advance the relationship, but Karen publicly announces her intentions toward Jun'ichi. Fuyuhiko later confronts Jun'ichi regarding his feelings for his sister, advising him to make a choice. Following Nagomi's suggestion, Yuuhi visits Jun'ichi's bedroom at night dressed as a maid, allowing the pair to grow closer despite initial awkwardness. The following evening, Yuuhi departs to report to her family, leaving Jun'ichi alone with Minato. Seizing the opportunity, Minato expresses her feelings for her brother, while Jun'ichi remains uncertain about his own emotions toward his sister.
