well, we can't always judge a person based on their past, people change just like time, if you are always going to despise a person because you don't like someone they were in a relationship with in the past, you will be very disappointed, because it's common for people to make mistakes in relationships when they start their first or first dates, all because they have no experience, they surrender in the moment, they act on impulse, they don't think about the later, if they can regret it in the future, then after a while , she finds the right person and thinks to herself: "Do I really deserve this face? I've made a lot of mistakes in my life"
That's where a sentence comes from that I thought: "It's not worth erasing or fixing past mistakes, if we can be better in the present"
Did Chloe make a mistake? Yes, but she regretted it, and she showed it when she started dating the mc, that was redemption, that was learning for her
It is worth noting that the same goes for Nora
