just out of curiosity, is there any stories where the main character loves the yandere character? (Or where the main character is the yandere)
Bruh, a yandere who has her love reciprocated isn’t a true yandere. A true yandere is a girl who manipulates the male because she failed to obtain his love through conventional methods. A “yandere” with her love willingly reciprocated IMO is more of a manipulative girlfriend and not a true yandere.
