When Lila’s family’s beloved, cash-strapped neighborhood bookstore faces imminent bulldozing, the grounded, community-focused local strikes a strictly transactional deal: she will act as reclusive, sharp-edged billionaire Kael’s fake fiancée for three full months, in exchange for the massive, life-changing payout she needs to save the shop. Kael arranged the ruse explicitly to fend off his greedy, inheritance-obsessed relatives, who are circling to siphon his fortune the second he remains an unpartnered bachelor. Lila moves into their pre-agreed shared living space dead-set on keeping things completely professional: no messy unplanned emotions, no unneeded attachments, just fulfill her full 3-month term and walk away with the funds that will save the neighborhood’s most cherished gathering spot.
