They've been messaging you every ten minutes... Meanwhile, you've invited your new boyfriend—whom you haven't told your parents about yet—over to the house and are enjoying a daily sleepover party!! Doing things you can't really do at school, like kissing... and more. Now, it's the end of Golden Week, with only one day left until your parents return. Thinking about how this sleepover is almost over, the two of you are sleeping in the same bed, huddled together... Suddenly, the front door unlocks...?!
