After I Transmigrated into a Book as the Villain, I Could Hear My Girlfriend's Thoughts

After transmigrating into a wish-fulfillment urban novel, I discover that I have all kinds of ties to the heroines.

[Congratulations, Host. You have obtained the Affection System.]

[Reach 80 affection to receive a regular reward.]

[Reach 90 affection to receive a mysterious reward.]

The higher the heroines' affection for me, the better the rewards I get.

Now that I have a System, obviously I have to take on the protagonist.
