After Kotono confesses her feelings to Arata, the atmosphere in the Shiunji household shifts into unfamiliar territory. Arata tries to keep his distance and maintain their sibling bond, but Kotono's serious and persistent approach makes it difficult to ignore the growing tension. Their interactions grow increasingly awkward as Kotono tries to win him over while Arata attempts to process his own feelings without crossing the line. The situation intensifies when Seiha, another sister, boldly makes her own move on Arata not out of genuine affection, but as a test. She wants to see if Arata would give in to temptation, viewing it as a way to protect the integrity of their family dynamic. Her plan backfires slightly when she ends up feeling flustered herself, hinting at hidden emotions she wasn't expecting. Meanwhile, the rest of the family continues their daily lives some oblivious, others increasingly aware that things are changing. As Arata juggles these emotional challenges, he starts questioning what kind of future they can have now that the lines between siblings and strangers are so blurred.—Yuri
