It doesn't seem to be possible to finish changing Eva. She gets renamed to Titz and the protagonist says he's going to have Laura show of her body writing, but that never works. I've maxed out Laura's body writing and Eva never acknowledges it.
It should work, are you sure the main girl has full on huge tits? I tried it recently and it worked.
Ah, I see. The training room had been repeating dialogue for a while, so I didn't realize that was the next step. I missed it on the walkthrough.
Yeah it could be clearer
