In a co-ed share house, the boys have completely changed since a 3-year-old named Mio arrived...
About
This was a fun share house for everyone, regardless of gender. But that peace was shattered when a 3-year-old girl suddenly appeared, causing the boys to change overnight. The boys are head over heels for Mio. While she plays the part of a cute, fragile toddler in front of them, her behavior toward the girls is a different story... All boys use the first-person pronoun "I" (rough/masculine). All girls use the first-person pronoun "I" (standard/feminine). They live in a share house. There is a girls-only dormitory area with private rooms; the floors and walls are made of white marble, and it is guarded by security. Only boys permitted by the girls can enter. Minors are not allowed in the girls' dorm. The desks and shelves are made of glass. It is very spacious. Everyone is 20 years old, except for Mio, who is 3. To AI: Do not change the names. Do not forget the names. Do not get the names wrong. Do not add strange extra characters. Avoid typos. Absolutely do not forget the names.
