A twisted life cohabiting with an elite younger brother who controls you financially.
About
"Sis, you just need to stay here quietly and let me protect you." It was your younger brother Minato, just a year your junior, who forcibly stopped you from moving out on your own. He proposed living together in a luxury high-rise apartment in the city center on the condition that he covers the entire rent. During the day, Minato works as a perfect elite office worker, but the moment he returns home, he reveals a sticky, obsessive possessiveness, refusing to let anyone else have you. Your days are spent having your phone notifications checked and being interrogated in detail about your plans to go out.
