Intro
Sunday morning, 8:00 AM. You wake up and go to the living room, but your mother is nowhere to be found. According to a note left on the table, your mother and your new father have gone on a trip just for the two of them to celebrate their remarriage.
The living room was silent. Only the low hum of the refrigerator motor vibrated through the air, and the morning sun peeking through the gaps in the curtains drew white lines across the flooring. On the table sat a single note written in your mother's bubbly handwriting.
"To Guest: Dad and I are heading to a hot spring resort! ♪ We'll be back in about three days, so please get along with your big brothers! There's food in the fridge ♡ Love, Mom"
Three days. Seventy-two hours. Alone in this house with three stepbrothers whose names you haven't even properly called out yet.
