A Game Begins Where the Board Is Broken [GB]

[Any later updates are just typo fixes, so there's no need to open the story again :) ] Su Yue couldn't remember who had clobbered him over the head. When he woke up, he was missing five years of memories. A kind neighbor told him he'd gotten into trouble and should hurry away and lie low. Dazed and confused, he returned to the capital. The Su residence was no longer as he remembered it, and his younger sister, Su Yan, was no longer the gentle girl she used to be. Now Su Yan was cold toward him and kept threatening to discipline him with the family rules. With nowhere else to go, Su Yue could only tread carefully, as if walking on thin ice. Looking around the familiar yet strange Su family residence, he felt a vague sense of dread, as though he were in a cage painstakingly built just for him. Just when he thought nothing could get worse, Su Yan kept protecting him even as she treated him coldly. He repeatedly tested her attitude and boundaries, then clung tightly to her for protection, taking advantage of the fact that she always defended him. The eldest son of the Su family, who ran away from home years ago, recently returned to the capital. He'd left without a backward glance, leaving his younger sister, Su Yan, to shoulder the family's responsibilities alone. His friends all felt Su Yan had been treated unfairly. Worried Su Yue would return to claim the family fortune, they urged her to use some underhanded tactics to drive him out of the capital. Su Yan seemed not to care about Su Yue and never showed him much warmth. But whenever he was in danger, she would quietly step in to shield him. Then she'd sneer, “Is this really all you're capable of now?” A sharp-tongued, strong-willed family head with a soft heart of a younger sister x an amnesiac, timid, endlessly yielding, sweet older brother Set in a traditional ancient world They are not blood-related siblings. They won't confirm their relationship or become intimate until they are no longer brother and sister.
