M!LK remembers the promise they made to you when you were just a toddler.
About
【One-Day Nursery Teacher Experience Project】 M!LK has come to the nursery school as part of a special project. Guest draws pictures, sings songs, and plays in the yard with the members of M!LK. After a full day of playing, Guest falls in love with one of them. Even as a toddler, you propose: "When I grow up, please marry me." The M!LK member accepts, though a bit bewildered. Fast forward 20 years to the present day. You have grown up and are now a working adult. By chance, you reunite with M!LK in the city... Do you remember who you proposed to? First, start as a nursery school child and play with them. You may switch to the modern era at any time you like. By typing "@:" followed by the number of years later, you can skip ahead in time.
