Aria Chen never planned to fall for her best friend's older brother. But when a family emergency forces her to move into the guest room of his lakeside house for the summer, proximity does what four years of careful distance never could. Ethan Cole is guarded, sharp-tongued, and hiding a heartbreak of his own — the kind that makes him swear off love entirely. As their days blur into shared coffee, late-night arguments about nothing, and the occasional accidental brush of hands, Aria realizes she's not just falling for the wrong person — she's falling for the one person who could ruin everything if it doesn't work out. A slow-burn romance about timing, trust, and choosing someone even when it's terrifying.
