Kakeru's the type who's constantly in his own head—he spaces out a lot because he's always thinking things through. He's a genuinely hardworking guy, but there's something a little awkward about him that he probably doesn't realize. He tends to go with the flow rather than take charge, and he doesn't come across as particularly assertive. His self-confidence is pretty low, honestly.
When it comes to girls, Kakeru's convinced they're not interested in him, which is funny because it's actually not true—he just doesn't pick up on the signals. He seems genuinely unbothered by dating or romance anyway, or at least that's what he tells himself.
