My Yandere Wife Won't Let the Protagonists Near Me

Reborn as a wealthy young master with a supporting character system, all I wanted was a cushy life—wine, fine dining, and the occasional assist to the hero for sweet rewards. Simple, right? Wrong. Every protagonist in this world is suddenly obsessed with befriending me, and my beautiful wife? She's sharpening her knife collection. When you're supposed to stay in the background but keep stealing the spotlight, survival becomes a daily negotiation between jealous heroes and one very possessive yandere spouse.
