MIDV-876 _My sister Yoru Tsukumo is a spoiled maid

Originally an autistic young man, Hashimoto had no other friend than his younger sister Truc Mang. However, Mang is different from his brother, always active, a million-view cosplay idol with a huge charity work record. Despite doing so much charity work, Mang still could not find a way to cure Hashimoto's illness. One time, someone told Mang to buy a cosplay maid outfit and then gave her brother Nang Cuc Plus medicine to nourish his kidneys. Please look forward to what happens next, hihi...!
