This dude lives in a high-rise in Tokyo and owns a car. Why did he react like she was being silly when she correctly guessed that he's rich?
He's not rich. He's merely a salary man (who even admits he skips on overtime to go home early at the "detriment" to his career). You have some misconceptions about Japan, too. He's unmarried, has no expensive hobbies and generally just goes to work and goes home. He doesn't have a lot of expenditures. And he does not live in a "high rise," it's a <10 story apartment complex. Although you are right that he lives in Tokyo and he even lives within sight of the Skytree which is... some prime real estate. Still, looking around quickly, the rent is nothing that a salary man couldn't afford.
Also, his car is a Kei car. Quite literally it's a micro-car (smaller than even subcompacts) that run on engines that have less output than high performance motorcycles (seriously, few have an engine larger than 700cc). They're cheaper than most cars (even domestic ones) and are obviously fuel efficient and until recently (around 2014) were very light on taxes to the point where it made more sense to buy a Kei if you could over a motorcycle or scooter. Nationwide about 40% of households that have a vehicle have a Kei car, and in some areas (rural mostly and some city) it's even higher with almost everyone that does have a car having a Kei. In fact, his Kei looks like almost exactly like a Daihatsu Move Custom. And while it is more expensive to own and drive a car in Japan (taxes, license, fuel price, ect.) than most nations, it's still a very middle class thing. Hell, plenty over lower/lower-middle class Japanese still have a car, especially a cheaper one like a Kei car.
