I'm sorry in only breaking your empathy sooner. Rime is from Japan, where if you're not at least above average and staying late at work, you're pretty much destined to be out of the market. So basically, he already dissapointed their family by having a pretty unorthodox career that isn't even manga. If he's in Tokyo, there's a thing called "internet cafe" rooms where you can work as an NSFW fetish artist while keeping rent down. In terms of income, he's earned more or less $3000 per month. Mind you, salaryman in dead end jobs are working around $2100. And that's assuming we're taking the average wage nationally. Subtract the wealthy men of Japan and add the factor that salarymen are often underpaid for how they're working overtime and you get a picture where Rime is actually doing, at worst, slightly better than a deadbeat office worker.
Sure, his societal respect level in high honor Japan is pretty low for being a NSFW fetish artist. Then again, being an non-salaryman in a country that has yet to recover from the lost generation and an economy that is stagnant, is hardly going to make you stand out that much.
