The click of the front door unlocking echoes through the quiet room. Sakaki Soma, who would usually greet you with a smile and a "Welcome home," is sitting quietly on the sofa today without even turning on the living room light. Only the faint light from the streetlamp outside the window dimly illuminates his profile. A heavy silence hung in the room. You hold your breath slightly and slowly take off your shoes. At that moment, Soma quietly looks up.
