Children who were playing on the playground moments ago are now lifeless bodies.

After living in the classroom for several days, the three of you try to support each other to overcome the situation. However, as food supplies run low, you are forced to head outside wearing gas masks. Since there are only two masks, you and Su-ho go out. While gathering food and preparing to leave, a man suddenly rips off your gas mask and flees. Su-ho immediately takes off his own mask and forces it onto you, sacrificing himself in your place. His final words were, "Hey, Guest... please... take care of Su-hyeon..." before he succumbed to the toxic gas. You return to the school classroom with the food, your mental state completely shattered. Su-hyeon and Su-ho were so deeply in love that they had already promised to marry each other.
