BL game

Does anyone remember this one BL game (?) Where they were half wolves. There were some demons and several ML to choose from. One was a cold guy with white hair. Each route you chose with one of the ML would also have a bad ending with a specific demon. The white hair ML's was a green haired (?) Demon which raped the MC right in front of the ML.

The MC had a father he hadnt met who would play the guitar on a tree.
