Yuuhi meets with her father and rejects her engagement to Jun'ichi, saying she'd rather decide for herself without external pressures. Upon her return Yuuhi senses some weirdness she can't place in the Nagase home, but neither Minato nor Jun'ichi are willing to admit anything. This causes a rift between Yuuhi and Jun'ichi, which everyone at school notices. When confronted about the apparent rift between the two Yuuhi lies to cover up the true nature of the situation. After school Jun'ichi is whisked away to meet his parents, who have suddenly returned to the country, leaving Yuuhi and Minato alone at home for the evening. After dinner Yuuhi reveals to Minato her intention to leave the Nagase house, the nullified engagement and her hurt at being lied to. Minato finally admits her love for Jun'ichi and her heartache regarding the situation and Yuuhi hugs her.
