Shu wouldn't consider himself open about his secrets. He couldn't tell his best friends, Valt would just blurt it out, and Xander lives to far away for him to bother confiding in him, as Xander rarely checked his phone, and was actually lightly annoyed when called in the middle of training, so Shu aboided ever calling him. Ever. This secret in particular was one he didn't think he could tell anyone, until today. One of his favorite YouTubers had once said, "But eventually, the jig will be up and they'll expload into a million tiny post-it note sketches." Well, that's exactly what just happened. Hehad finally brought up the curage to bring his art bag, so he could draw while the others battle. Then, Valt caught sight of him sketching on one of his post-it notepads, and when Valt started asking questions, the whole beyclub, and the twins turned around to look at him. That's when all hell broke out. He ran off to go home, the little notes flying everywhere. So no everyone knew he liked to draw, he drew comics every now and again,h he loved cats, and loved dark magical girl anime, and basically just anime in general.
(Yeah that's it. Shu just gets really awkward and tense around his friends, or whenever the psot-it note disaster is brought up.)
