Old Lover Returns as Crabapple Blossoms Fall

Old Lover Returns as Crabapple Blossoms Fall Plot:

Su Wan has guarded her grandmother's old house with a crabapple tree for ten years, waiting for Gu Ci—who left overnight due to family debts, promising, "When the crabapple falls again, I'll come back to marry you." This late spring, just as crabapple petals drifted into the windowsill, Gu Ci really stood at the courtyard gate, but with a woman in a wedding dress on his arm. He looked at the crabapple-patterned letter in Su Wan's hand, furrowing his brows and saying, "Miss, do we know each other?" Yet Su Wan clearly saw the scar on his wrist—the one from saving her from broken glass years ago, still a pale pink mark... Did he really forget, or is there a secret behind his departure that even he dare not reveal?
