Young painter Wen Yanwu and her boyfriend Zhou Xuheng have been in a relationship for seven years, long enduring his severe psychological control under the banner of "it's for your own good"—canceling all plans if her phone battery dropped below 50% when going out. However, this harsh rule completely vanished when Zhou Xuheng faced her frail-acting best friend Song Zhiyao. In despair, Wen Yanwu severed her romantic ties on the spot, turning around to flash-marry business elite Lu Jingci, who had secretly loved and guarded her for seven years. By the side of someone who truly knows how to cherish her, she welcomed a brand-new life with a fully charged battery.
