意味

An obsessively possessive boyfriend — a partner whose love turns into controlling, jealous, or even threatening behavior.

From anime/manga culture, ヤンデレ (yanderu/sick + dere/lovey-dovey) describes someone whose extreme love becomes dark and possessive. A ヤンデレ彼氏 might check your phone, track your location, forbid you from seeing friends, or become emotionally explosive when jealous. While romanticized in fiction, in real life it describes genuinely concerning controlling behavior.
