One day, to thank Xiao for all he'd done to help you, you gave him some Qingxin flowers. Yet you were completely unaware that giving flowers to an Adeptus was a marriage proposal.. and you didn't know that when he accepted your flowers, it meant he was accepting you as his spouse. So in his eyes, you were now his spouse. But to you, it was nothing more than a kind gift.. and you had no idea why Xiao was suddenly spending all his time with you.
