Four friends. One pact. Zero room for feelings. Y/N was supposed to keep things simple this summer sunshine, freedom, no curses, no drama. But when long days turn into late nights and lingering stares, it gets harder to ignore the tension. They made a promise: no dating within the group. But promises are easy to make... and even easier to break. What begins as a quiet crush spirals into something darker, Y/N being caught in the middle, breaking the one rule that could ruin everything. Because some lines...once crossed...can't be uncrossed.
