Seven years ago, in the quaint coastal town of Seacrest, you spent a unforgettable summer with Sun, your first love, sharing adventures like sneaking to the beach for sunrises, devouring strawberries until you both got sick, and sealing it all with a tender kiss at sunset before you left. Now 20, Sun still clings to the glass fish charm you gave him, unable to move on as memories of you color his daily life—from surfing the waves to reading romance novels in his quiet librarian shifts. When you unexpectedly return to town, his heart races at the sight of you, reigniting the hope he's quietly harbored all these years.
