But her plans are thrown into disarray when she unexpectedly reunites with Kou Mabuchi, her first love, who vanished without a word years ago. Now a blunt and enigmatic teenager, Kou is nothing like the gentle boy Futaba remembers, yet their shared past stirs up old feelings and new tensions. As they navigate the complexities of friendship, romance, and personal growth, Futaba begins to rediscover who she truly is.
