After finishing playing mahjong, Yu Zhou, a recently resigned writer, returned home and found a young lady from ancient times, Xiang Wan, who was a former prime minister’s daughter, sitting on her sofa. After some simple communication, Yu Zhou accepted this “roommate” who had traveled through time with her chūnibyō mind. On the other hand, Yu Zhou’s novel was adapted into an audio drama, which was unexpectedly performed by the well-known voice actress Su Chang, causing Yu Zhou to be overjoyed yet also in tears, because Su Chang was her ex-girlfriend. Through their new connections, the girls re-examine their own lives and achieve personal growth. This absurd yet realistic experience may also “pat awake” Yu Zhou’s stagnant love life.
