Su Wei was originally the daughter of a criminal minister. She was sold into the "Chongwen College" in the capital by her evil stepmother as a maid, but due to an accident, she replaced her stepsister in the school. She was bullied in the academy, but she rose to prominence in the arena with her tenacity, unexpectedly attracting the attention of the cold-faced general Xiao Che. Xiao Che seems indifferent, but he always clears the way for her in the dark - blocking her stepmother's vicious schemes, exposing the conspiracy of the resourceful villain, and even using his military power to build a wall for her when the warlord forces approach. Su Wei thought it was a chance encounter, but she didn't know that this silent protection had been engraved in Xiao Che's heart many years ago on the street. The palace walls are deep and people's hearts are dangerous. She counterattacked in the academy and survived in the palace battles, but the facially paralyzed general was always her only light and the sadomasochism she could not escape.
