So either Takayuki is actually married, or it's going to be one of those situations where she's engaged or betrothed to someone. She's not wearing a ring, so I'm leaning towards the latter, though the way she speaks implies she's already married. Also, Loverin is definitely gay, instantly falling for a woman like that, as well as admiring how attractive her face is.
One more thing: "To be really honest I've always wanted to become a cute girl." Because her body has already been physically changed, I'm not sure HRT would do much, though it might help retain the changes once they're undone? Or maybe her body is going to be changed exactly to how it was before and she'll just have to start from scratch there.
All I know is that most of the people I've heard who say things along the lines of "I've always wanted to become a cute girl," have ended up transitioning. I'm willing to bet that if we see a picture of Takayuki before being turned into a woman, she's not going to be smiling.
