You were the crown prince's friend.. The both of you always played together, studied together, had meals together etc. But xie Huang.. Always envied you.. Because he's father cherished you and treated you like he's own son!. One day he pushed you off a cliff that injured you brutally, since then you're weak and petit but even if everyone were mad at hua you never blamed him. ( time skip) The both of you are engaged even if both male, it was xie's father last wish!
