"Sorry's Not Good Enough"
Thinking about Harry growing up hearing ‘Sorry’s not good enough’ and just learning it’s pointless to apologise, as it’s just spat back in your face anyway.
Thinking about him really struggling to apologise to people, and mainly doing so by buying people gifts or making reconciliation gestures of some kind.
Thinking of him building a relationship with Draco, who, for all his family’s faults, always taught him the importance of apologising to the people you love.
Thinking about Draco getting more and more frustrated when, no matter what, Harry doesn’t outright apologise for things. He changes his behaviour, sure, but it still stings and reinforces old stereotypes — the golden boy, too high and mighty to consider how a lowly ex-death eater feels. And what stings more is that everytime they fight, Draco makes sure to apologise to Harry.
Thinking about it all coming to a head after they have a stupid fight about something that doesn’t even matter, and Draco’s still a little too amped-up. When he apologises and Harry graciously accepts, saying it’s okay, Draco just sighs, the spark of annoyance reigniting in his chest instantly. Thinking about Harry just flinching, trying to shrug it off, appease Draco in some way, whilst fighting off the shame his Aunt and Uncle drowned him in as a child. Thinking about everything ramping all the way back up until they’re both yelling at each other again, and Draco just leaves, screaming about how he knew Saint Potter could never truly value a death eater as a friend.
Thinking about Harry destroying his house until all he could do was curl into a ball and sob.
