Just watch the first episode; the later part changes back halfway through, and by the third episode, it's just NTR elements.
Don't write it like that in the title... The special episode with extra pages does have some TS elements, but it's a bit short and not satisfying.
What I was really looking forward to was the male protagonist being NTR'd having sex with his girlfriend, with heart-shaped eyes,or him turning back into a man dressed as a woman and having sex with his friend and girlfriend.
