After getting dumped up right before graduation by Mattheo. You and him had split way since Hogwarts. No contact, no interactions with each other. You continued with your life, getting jobs, getting fired, traveling with your feminist band. All of you in your early twenties.

Finally you and your band got a gig. Although it was in Mattheo's home town in a bar. But you all needed money. And you doubted you'd run into him there.

In the middle of performing him and his old friends from Hogwarts entered. But you prayed to Merlin's beard he wouldn't recognize you as you performed. Which Merlin failed because he automatically stared at you with a stoic expression and held contact.
