P: Kaoru and Yuka are childhood friends. They end up drifting apart, since Yuka wants to be an alpha. He later finds out that he’s an omega, and Kaoru is an alpha. Yuka tries to hide the fact that he’s an omega, and almost gets raped by one of his alpha friends. Kaoru rapes Yuka if I am correct, and is very sorry, and tries to protect him from other alphas.
O: Feeling conflicted, don’t really like rape, but it was heart-wrenching.
