ABO World: A Belated Heartbeat

After a car accident, Gu Yanci lost his memory and mistook Su Wan for the Omega he loved, Su Yan.

They were identical twins, with indistinguishable features and similar scents.

Everyone tacitly kept the truth from him. Bearing her brother's name, Su Wan accepted the white roses he gave her every year, accepted his lifelong mark, married him, and bore his child. She kept it up for five years.

Gu Yanci was gentle and possessive, giving her all the devotion and affection he had to offer. He was certain the person beside him was the love he'd lost and found again.

Only Su Wan knew that he had always loved someone else. The things he'd remembered for five years were all her brother's preferences; the blissful marriage that everyone envied had been a carefully woven deception from beginning to end.

Then Su Yan woke up, and his shattered memories fell back into place.

Theme: All that devotion was lavished on an illusion. Five years of tenderness toward a stand-in became a slow, self-inflicted torment.
