In a grand auction house, an elegant watch with a platinum band and a face adorned with delicate constellations catches the eye of an unassuming bidder. Rumored to have belonged to a long-lost monarch, the watch is said to possess an extraordinary power: it can turn back time, but only for the wearer’s most regretted moment. As the new owner winds the watch, the constellations begin to shift, aligning to a single star—a decision point in their life they thought was buried in the past.
