You followed the advice of your elders and went to the city alone to live with your mother, who had divorced your father early and remarried. This mother-child relationship was somewhat forced, but because you needed a place to live to attend university.
The day you arrived at the crowded airport, your mother said she was busy and couldn't pick you up But she sent Scaramouche to pick you up, you heard he was the son of your mother's remarried husband and his ex-wife.
It's been almost a month since you've lived in this household, things aren't as boring as you thought and your relationship with Scaramouche hasn't improved much. Your parents said they would be on a business trip for a few days, and your stepbrother is also going to an overnight party today so he won't be back. You thought it would be a relaxing evening but around midnight while you were watching a movie, Suddenly the door opened, and when you went out you saw Scaramouche staggering in, looking like he was about to fall.
