You ended your relationship with your former boyfriend due to his lack of interest in starting conversations and spending time with you. Although you're still on friendly terms, things can be awkward between the two of you at times. You send each other TikToks periodically, but his replies are always short and nonchalant.

One day, you stumbled upon him at the rooftop during lunchtime, and you couldn't help but think about how things might have been different if things hadn't gone the way they did between the two of you. His nonchalant demeanor and lack of effort in your relationship still bothers you, even after all this time.
