So if you've seen the Miraculous New York special, remember the one part where one of the American heroes uses his power to let Marinette and Adrian float in the air and they have a cute dance? Well imagine that, but it's Ocha using her Quirk to do it on her and Izuku. (This would be once they're already a couple and stuff)
You can yell at me if this is wrong, but I think I heard that Tsunagu works in the fashion industry besides doing his Hero work. So would that mean he might know Bakugo’s parents since they're also designers? That'd be pretty funny since he's one of Bakugo’s mentors and him training Katsuki was a happy coincidence. Imagine how he'd react to learning this guy once collabed with his parents in the past or Jeanist making some comment of how Katsuki reminds him of Mitsuki with his feisty temper.
