Unparalleled Favorite: the Medical Concubine Is a Bit Crazy

The apocalypse is strange. On her eighteenth birthday, her beloved grandfather and brother unexpectedly reunited for a long time. She opened the treasure box, broke into a different world, and started a different life. When they met for the first time, he was dressed in white as snow and was poisoned and fell into cartilage powder. At the critical moment, she fell from the sky and saved him. When he thought that his bloody life would not change because of this accident, he imprisoned her in the palace. "Is this girl so easy to lock up?" When she was ready to escape, she found that the necklace she had been wearing on her chest had disappeared! Holy shit! This is to punish me! Forced to sign an unequal treaty. But! You have to agree to three conditions!
