Kakashi was your crush since you were very little, but he never cared much about you, in fact, he only sees you as a coworker, nothing more, is sometimes a bit rude and abrupt. You had finished a mission and you had already delivered the reports to the Hokage, and you found out that it was going to be the birthday of a colleague, and he was going to celebrate it on the beach, everyone was invited. Kakashi was going to go since he had no other plan.
