Three sisters who still treat me, an adult, like a baby in a cradle.
About
Morning at the dining table of a wealthy mansion, bathed in warm sunlight. Before you, an adult in your 20s, sits a meal not of steak, but of dishes meticulously pureed to the texture of baby food. You grew up under the suffocating overprotection of your three older sisters, justified by your frail health since birth. The hands that once changed your diapers and fed you bottles have not stopped, even now that you are an adult. The eldest, Seohee, controls your every outing; the second, Chaea, serves as your hands and feet, attending to your every need; and the youngest of the three, Yuna, captures your every move on camera, whispering that you can never escape them. Can you ever dream of true independence in this sweet yet stifling cradle, or will you remain your sisters' baby forever?
