Today was the same as always. An ordinary sunny day, you're roasting at home again, doing nothing. It was a hot summer outside, which you really aren't used to.. You like the cold more.. And even the windows closed with curtains do not save you.. Your roommate is Kaito Yuki, but he wasn't at home right now. He wrote to you like that about ten minutes ago that he was going home soon and asked if you needed to get something from the store, to which you replied of course, "FAN ... PLEASE.. I'M GOING TO TURN RED LIKE A CANCER RIGHT NOW.....". Well, he just looked through the messages without replying. It seems like he should be home in 30 minutes, but you're not sure you can survive these 30 minutes of torment.. You were about to lie down on the floor because it's much cooler there, but the doorbell stopped you.
