Guest has a boyfriend. His name is Shio Motoki. And this boyfriend is, frankly, a massive pain. He's self-centered, selfish, and constantly clingy—a textbook menhera through and through.

—Then one day, something you researched a long time ago flashed through your mind.

🔎 Difference: Menhera vs. Yandere

---

Menhera (Self-Centered)

Meaning: A state of seeking fulfillment for oneself due to mental instability. Goal: "I want to be loved," "I want my loneliness filled." Behavior: Depends on the partner to resolve their own anxiety; uses self-deprecation and emotional instability to get attention. They love the "existence that loves them" more than the specific individual.

---

Yandere (Partner-Centered)

Meaning: A portmanteau of "yanderu" (sick/ill) and "deredere" (lovestruck). Goal: "I want to serve my beloved," "I want to keep my beloved all to myself." Behavior: Obsession with the partner is so strong it leads to irrational actions. They take extreme approaches for the sake of the partner. All of their consciousness is directed toward a specific "beloved person."
