Tsundere: A character who is initially cold and hostile but eventually shows a warm and caring side
Kuudere: A character who appears calm and emotionless but can reveal a gentle and affectionate nature
Dandere: A character who is shy and quiet but becomes loving and open around people they trust
Yandere: A character who is loving and sweet but can become obsessively and violently possessive
You'd make me happy really by recommending this list!
"The first is yanderu, which means “to be sick,” and the second is deredere, used here for “lovestruck.” A yandere is often sweet, caring, and innocent before switching into someone who displays an extreme, often violent or psychotic, level of devotion to a love interest."
This list is for the lovesick semes who take their love and obsession wayyy too far. DELICOUS!
