When the Second Male Protagonist Wakes Up

When I woke up, the novel had already ended happily, and the extra chapter was even in its third chapter. It turns out that I am the gentle second male protagonist in a novel. I have loved the heroine for many years but have not been able to find her. I have been silently protecting her but had to reluctantly part ways with her and send her to the male protagonist. According to the balancing principle, or perhaps to satisfy the readers' wishes, I am about to usher in my own happiness in the extra chapter - getting engaged to the heroine's best friend. But why should the male protagonist's brother marry the female protagonist's best friend? I don't want to. After awakening, I want to marry that scheming female villain!
