[Palace fight + revenge + ambiguous pull + little mom literature + sweetness + 1v1 + two-way + yandere male protagonist]
Song Nanzhi was originally the legitimate daughter of the General's Mansion, but she was not welcomed because her mother was once captured and sent to the enemy's camp.
During the most difficult time, she met Shen Changmu, the Prince of War. Shen Changmu saved her and her mother's lives, so Song Nanzhi fell in love with him and made a private life-long marriage with him.
But the hemp rope was broken at the thinnest part, and his mother died in the fire. After investigating, Song Nanzhi decided to take revenge.
So she entered the palace alone, married the emperor and became the imperial concubine. Shen Changmu was unwilling to return to the palace and became yandere.
After the emperor passed away, Shen Changmu sat on the throne, but he pushed the concubine Song Nanzhi and his nominal baby mother into the corner: "Song Nanzhi, do you still miss my father now?"
