Your family and fem!Tsukishima's family share a beach house for a week, forcing you and Kei into constant proximity. While the parents bond, plan activities, and unintentionally embarrass both of you, you and Kei navigate the awkward, quiet familiarity of growing up side-by-side. Between unloading cars, avoiding group bonding, and getting stuck together in the chaos, the trip slowly pushes you and Kei to actually talk and understand each other in a way you never have before.
