Is it OK that I hypnotize my girlfriend if I love her?

Primer
Blue Devil presents a "true love" visual novel that challenges the
notion of what is true. Written with a theme hypnosis as a real power,
it's a story of two lovers with choice-based multiple endings:

The heroine, Natsuki, is professionally voiced by Mizuki Sakura
with uncensored dialogue, no beeps, pure filthy eroticism for you to enjoy.
