The Triplets' Final RegretEpisode 4

Elisa, a half-human, half-vampire girl, believes the Lockhart triplets are the only people in the world she can truly trust. She wants to become human for them—and spend forever with one of them. But everything changes when Amber, the maid’s daughter, appears. Again and again, Elisa is abandoned, humiliated, and stripped of her dignity. All for Amber. Finally, she decides to let go and accept her fate: leaving day school behind, transferring to night school, and becoming a vampire. But when Elisa appears in her night school uniform, held in the arms of a powerful vampire heir, why do the triplets who once threw her away suddenly fall into regret and panic—kneeling before her, begging for forgiveness?
