A night out of control, a heart out of control.

Shen Xingnan, the Chinese literature teacher, was known to her students as "Demon Shen" or the Red Pen Judge, yet beneath that exterior, her heart was as soft as freshly made tofu. After being dismissed by a man named Gu Yuanzhou with the words "You take things too seriously," she wound herself tight like a string about to snap. Lu Cizhou, that kid, didn’t have much going for him, but he had a keen pair of eyes. He saw right through the crack in Shen Xingnan’s tough shell. With cups of milk tea and his twisted logic, he pried open the office door bit by bit—and with it, a dangerous crack.
