You need to have seen
Jill's lewd in
EP.6 and not be
DIK.
The guy wants to be invited by
Bianca and rejected by
Jill. You are correct, to have
Jill's lewd in
EP.7 you can't be
DIK and you need to have seen
Jill's lewd in
EP.6 (the
Jill route is hell to follow, very confusing). I don't think it's possible to be
CHICK at this point in the game. I don't know why he wants to be rejected by
Jill, is it because he has no dignity?

To be rejected by the Goblin Princess, what a slow and cruel death.
[UPDATE]
I looked at the game code and it is possible to get the
EP.7 lewd being
NEUTRAL. Maybe you can do it?
