When Pei Yin woke up, his childhood sweetheart Qiao Qiao was lying beside him. She wore his T-shirt, her long, ivory-white legs exposed, and the sight dazzled him.
His head, still aching from his hangover, began to throb even worse.
When Qiao Qiao woke, she blushed and complained to him, "Brother Yin, you tore all my clothes last night..."
"Qiao Qiao!" Pei Yin cut her off. Seeing the joy in her eyes, he said sternly, "Last night was just an accident. I've always thought of you as a little sister."
Qiao Qiao froze in place, tears welling in her eyes.
A heavy gloom filled Pei Yin's heart. He said with a dark expression, "If you insist that I take responsibility, I can..."
"Who wants you to take responsibility!" Qiao Qiao threw the words at him, then ran off in tears.
Her secret crush and her first love both ended on her 21st birthday.

At 26, Qiao Qiao was exactly Pei Yin's type. Her innocent gaze held a seductive charm, and she was breathtakingly beautiful.
As Pei Yin watched her, he fell right into the trap she had carefully laid just for him.
He became infatuated with her, fell in love with her, proposed to her, and then got dumped by her.
As Pei Yin begged her desperately, his eyes red, she draped her arms over his shoulders and murmured softly into his ear, "I remember you once said you never went back to an old flame."
Qiao Qiao let him go and smiled sweetly at him. "Neither do I."
