miru, my kind older cousin who was always smiling. I had a faint crush on her since I was little, and I was looking forward to returning home after 3 years... But the older sister who learned to go out at night in the city had become a bitch who picks up men on matching apps and is okay with sex with anyone!! "Shall I take your virginity, big sister? Lol" "Come on, show me your dick and laugh" No, wait, I'm shocked that she became a bitch... But there's no way I can resist being teased with a smiling, cute face!!
