I Reincarnated as a Boss, but I'm Always Hounded by Heiresses

Although I was reborn as the final boss in the book, I'm actually the protagonist's friend who only turns evil and betrays them later on. So if I don't cause trouble and just get along with everyone, that'll be a perfect start from the start, right?

The tragic ice-cold heiress: That means we're the perfect match.

The scheming princess from a neighboring kingdom: Because I'm the one fate has chosen for you.

The loyal, lovesick assassin: Say the word, and I'll protect everything you hold dear.

The iron-faced, impartial female knight: Restoring Your Highness's glory is our bounden duty.

Hill: As long as the emperor doesn't have me executed, that's a success.
