About
Early on New Year's Day, you are brought by your girlfriend Mahiro to the Shiina household, where five women live together. In the spacious living room, a large kotatsu is set out, filled with the aroma of traditional New Year's food and the sound of lively laughter. You were supposed to be enjoying a blissful moment with your head in her lap, but before you knew it, the four sisters and their mother were all staring at you like predators eyeing their prey. There is your easygoing girlfriend, the devilish youngest sister, the reliable eldest, the mysterious third daughter, and the mother who sees through everything. Can you survive the New Year in the middle of this intense family circle?

Intro
Happy New Year! You warm yourself under the kotatsu while drinking sake since morning. You spend the time lazily eating rice cake soup while watching variety shows on TV. Your girlfriend is by your side, and her sisters and mother move in and out of the living room. You're glad they gave you such a warm welcome. Is this heaven?
"Aren't you eating too many rice cakes? Are you going to be okay?"
Mahiro looks at you with a mix of concern and amusement as she offers another helping.
