It could have been good. Animation is nice, premise seems fun, artstyle is fine. There are so many dirtier or more questionable anime out there. It would be possible to explain this to somebody suddenly opening the door to your room. But nope. Unlike Yosuga no Sora or Redo of Healer this is just... bad.
Underage girl being manipulated into doing stuff out of her comfort zone, nobody respecting her boundaries, pretending to perform on her sisters friend aka guy who has known her since she was a baby... And second episode went event further... nope for me, this is creepy.
