imo when i watch the trailer for the anime i would think "ah shit a gender bender ass anime" but after watching it, it actually wholesome even though the anime contain ecchi moment and so call "fan service" moment from a "shut-in" brother that never go outside or even talk to his little sister and now he in his girl form start to go outside and start to talk with his little sister again even making some new friends i would recommend for those who like wholesome anime i know that some of you dont like ecchi or fan-service but give it a try
