Hmm the concept is nice and i like that there was a drama CD, honestly I thought it was shounen ai from the lack of sex scenes and I feel the villainous sister archetype wasn’t fully resolved. author should have showed more dynamic of the sister really went out of her way to break them up she had more emotional involvement and o really wish they touched up on that to add more layers to our characters. Anyways it felt a little flat for me but it has potential too.
