I have a feeling that we will be seeing Lamia's journey through becoming a knight and gets into a duel with ML but in the end, she still dies regardless without even loving ML? Of course, ML rewinds time again but instead, Lamia has a dream of her knight past, not the dream where ML calls her name out. She thinks that she had a bad relationship with ML so this time, she avoids being a knight and either continues to be a noble or some alternative occupation (e.g. Mage). It's possible that she might have a "deja vu" feeling at some point?
