she THINKS she is straight but is really a lesbian and doesn't know it
Says who? Let's ignore the genre and our experience with these sorts of mangas and look at the situation from a more detached perspective - a young girl lures another young girl with money and slowly gets her used to escalating sexual acts, starting with skinship that the latter initially finds uncomfortable and eventually moving to outright molestation - and this is with around 3 months of time left in their deal. If you ignore things outside the work and look at it critically, it's really disturbing, or at least that's the way it seems to me.
Hindsight (which will come with time) and prior experience with the genre aside, "you are really into it, even if you refuse to acknowledge it" sounds like something a rapist would say. In fact, if the art style was different and the same things were portrayed in a different perspective, it'd totally be seen that way. I strongly ask you to shelf your gut reaction and take a bit of time to think it through, even if you reach the same conclusions at the end.
I am probably speaking to a wall, but it's really frustrating to non-stop hear the same copy and paste reactions.
