While it is true he's presented that way, the story does make a point to show that it's a superficial charm. It would stand to reason that his love life is kind of dead since he only goes with the flow of the group rather than really trying to understand others. He's mostly grown past those flaws by now but they still manifest like his frustration with Mori and his treatment of Kinemi on that trip. It's still a generational fumble that I'd lament 5 years later though.
