Men's Dormitory 306, Saint Siya College

Mo Han was raised as a boy by his mother from the day he was born. She is the only "only son" of Mo's chaebol and the heir to the first family on the rich list - mother and daughter have kept this secret for eighteen years. Now she entered the Saint Siya Noble Academy and lived in the same dormitory with four boys from prominent families and different personalities: the cold and dignified Wen Siyan, the wild and wild Lu Zhanye, the enthusiastic and cheerful Jiang Yuheng, and the gloomy and silent Ji Mingchuan. Among this group of glaring human beings, she must hide her gender, her heartbeat, and a big lie. What's even more difficult is that Chu Yunshu, the eldest daughter of the Chu family who has known her since childhood, also transferred here with the intention of getting married. The road ahead is long and startling at every step. But she didn't know that when the truth was revealed, some people had already chosen to be on her side.
