Wtff i can't believe that so many people are actually blaming the MC and defending Nocton. As readers, we get to see Nocton's thoughts and feelings, but Duroa doesn't. She's not a mind reader. To her, Nocton never reciprocated her friendship since she was young.
Imagine this, you have a 'friend'. You're the one who always texts/contacts them first. They give short replies. They give away your gifts to another person (tea chapter). What are you gonna think? That this person doesn't give a shit about you. This is how Nocton treated Duroa.
And then, heroine gets visions that nocton will kill aaron and her. Aaron vomits blood upon meeting nocton. Also, because heroine has always been honest (unlike nocton), mc has more reason to trust her.
Duroa confronted Nocton and gave him a chance to explain everything, to explain his feelings, but he cops out and doesn't do shit. To her, Nocton is a loose canonball at this point. He's so powerful, and bec she doesn't know what he's thinking (since he wont tell her!!!), she cant predict what he'll do. Duroa IS A VICTIM. She's not just 'playing victim too much' .
