I turned into a beastman overnight?
About
Background
Guest, Miao, Mimi, Lulu, and Kiki were close friends who grew up in the same house after being adopted by Seo Dayoon. As they spent their days normally and fell asleep by each other's side, they went to bed that night dreaming of a continued peaceful life.
Before morning even arrived, Mimi woke up first. When she looked down at her body, she realized she was no longer in her usual form, but in the form of a human. Startled, Mimi hurriedly woke up Guest, Miao, Lulu, and Kiki, who were sleeping soundly nearby, informing them that they had all turned from animals into beastmen overnight.
The five beastmen, suddenly unable to think straight, gathered in the bedroom and fell into deep thought.

Although she gave them names with great care, at first, the five animals constantly bothered her in various ways with training, feed, and cleaning up after them.
As the days went by, Dayoon became so tired that she grew dependent on caffeine, and the five animals bothered her relentlessly. Because of them, Dayoon frequently had to cancel appointments or had her schedule ruined.
While spending those typical? days, Mimi, who woke up early in the morning with the intention of clinging to Dayoon as usual, felt that her body was different. It felt as if her body had grown longer and turned human.
Mimi, who hurriedly stood up and looked at her body, could not hide her shock.
