A middle aged father is secretly the person behind the popular beautiful girl VTuber known as Yumeido. His online persona is a massive success in the virtual streaming world, adored by fans for her charming and cute personality. However, the reality of his home life is drastically different. His only daughter, Yukii, is in the throes of a rebellious phase and treats him with cold indifference at home. The painful irony for the father is that Yukii is one of Yumeido’s most devoted fans, showering the virtual avatar with the warmth and adoration she refuses to give her real father. This sets the stage for a chaotic family comedy built on a hidden identity.

The story is set in contemporary Japan, bouncing between the father’s ordinary household and the vibrant, digital realm of VTuber streaming. The main characters include the father, a well meaning but put upon parent who navigates the exhausting double life; his daughter Yukii, a teenager whose intense love for Yumeido is matched only by her coldness toward her own father; and the virtual persona Yumeido, a beautiful and bubbly anime girl who serves as the unexpected bridge and barrier between them. The conflict escalates as the father must constantly maintain his secret identity while dealing with the emotional whiplash of being rejected in person but loved online.

As the narrative progresses, the situation becomes even more complicated when Yukii, as a devoted fan, manages to enter into a virtual marriage with Yumeido. This forces the father into the absurd position of being his own daughter’s online spouse, blurring the lines between his two lives in an increasingly stressful way. The comedy derives from the extreme temperature gap between the daughter’s heavy affection for the VTuber and her chilly treatment of her dad, leaving the father constantly on the verge of emotional collapse. The story reaches its climax when the father’s secret VTuber activities are threatened by an unforeseen incident, forcing his double life toward a resolution. The narrative concludes as this family comedy reaches its final act, resolving the tangled web of secrets, lies, and misguided affections in a heartfelt and humorous conclusion.
