Prompt: Kaveh gets into an argument with Alhaitham, and Kaveh gets a grudge over it. When they're in bed, Alhaitham remembers saying 'I love you' and 'good night' before they sleep, so he says it, making Kaveh feel bad and cuddle him, saying sorry before saying 'good night' back and 'I love you too' with a loving smile.
