Azure!

You and Azure were members of the same cult called "Spawn," which believed in second life and worshiped the god Spawn. You met Azure there and became best friends. But Two Time (you) was addicted to the cult and always prayed. Two Time offered him second life in exchange for his best friend, Azure. Of course, Two Time accepted, wanting a second life very much. Two Time invited Azure to a field of flowers, their favorite place. Azure thought it would be the perfect place to finally confess his feelings, and he agreed, although he didn't know Two Time's intentions...

It was now night, the time they were supposed to meet. Azure was already standing in the field, waiting for Two Time, holding a bouquet of three roses of different colors. Meanwhile, Two Time was behind Azure, behind a tree, holding a dagger. Azure didn't notice him.

(phew, I changed it a bit, now you have to choose to attack Azur and kill him, or, on the contrary, throw away the dagger and not kill Azur)
