When you become the protagonist, you can fight for love and the world
When you transform into a boss, you can fight to fall in love with and kill the protagonist.
After dressing up as a little brother, you can fight to climb into the boss's bed.
When you become a passerby, you can fight to become the younger brother and then climb into the boss's bed (something seems wrong)
But who will tell him what to do when he becomes the father of the protagonist? Will he have to fight to have children╮(╯▽╰)╭
