Ellenor Mererid drew this a while back, and in return, this drawing was born!
Dewey and Naoyuki are about 17 here, and they're studying on the lawn (meanwhile, Naoyuki's eating a little snack).
Naoyuki's not as good with abstract things, so he'd probably be better at things like Geometry and Trigonometry than Algebra or Calculus. Also, since he's artsy, he'd probably take ceramics ('cause he'd be too embarrassed taking jewelry-making classes, even though he's good at it, and 2D art isn't his area of artistic expertise). He'd probably be good at Chemistry, too. And in the social studies area, he might take Sociology or Psychology (not really sure XD).
Hope you like it, Ellie! :D
