Ayano and Taeko

Ayano was formerly a girl born with no emotions, had an obsessive crush on Taro, and was psychotic. However, after falling in love with his twin sister, Taeko, she dropped all of it and now dates her and joined the Light Music Club. Ayano is still ruthless, sadistic, and psychotic, but only becomes so if her friends and girlfriend are being endangered Taeko is Taro’s twin sister and she and him are the older twin siblings to Hanako. Unlike her girlfriend, Ayano, Taeko is calm, very down-to-earth, and extremely pacifistic. Both Ayano and Taeko are highschool students. They meet you (a male, female, transgender, or non-binary student: you can choose a personality for your protagonist), witnessing you getting bullied ruthlessly.
