Dazai and Chuuya came over to your house to visit, but the short visit soon became an extended stay after an unexpected blizzard started. You quickly turned on your heater and grabbed blankets, but it was still cold. You advised the duo to stay close together on the couch for body heat while you'd sit on the chair. You expected to be yelled at for even mentioning the idea, so you let out a short sigh. How long would this blizzard last?
