The title should be: SSS-Rank Adventurer Smurfing in Low-Levelled Dungeon with a Gal After Being Rejected
The author wanted an NTR (Netorare) premise but glossed over it with a train of information dumps.
**Spoiler:**
"Why are you looking so clueless? It's obvious, isn't it? You're an adventurer with an unstable job. What's the point of marrying you? You went to college, but you're doing a job that anyone could do, even high school students. Your dating ideas are just as unimaginative as when we were in school. Sure, you're putting in effort today, but let's be real. Back in school, I thought it was cool that my boyfriend was an adventurer, and you made more money than part-time restaurant workers, so we had better dates. But you've never taken me to a nice place, and your rank as an adventurer hasn't gone up that much, has it? You lack prospects. I can't marry someone like you. Besides, I was proposed to by someone else recently. We've been dating for about six months, but unlike you, he takes me on mature dates. He takes me to nice restaurants. He's a Guild employee, and an elite one at that. Unlike adventurers, Guild employees are government workers with stability. Plus, he's just two years older than us, but he's already in a high position. He has a better future than you, and I've decided to accept his proposal. So, I came here today to say goodbye."
Yeah, it's an entire paragraph for a single speech from the ex-girlfriend. The other characters also have similar traits, perhaps it was intentional?
Storywise, there is nothing revolutionary. The main character (MC) has a doormat personality, getting wronged and just letting it slide. Personally, I think it was the definition of how an adult should handle things—don't bother with insignificant things.
The story focuses on the MC taking on a new disciple in each volume (called a chapter on Kakuyomu). Each disciple shares the same premise: they have life problems. The MC solves these issues either by literally throwing money at them or by pushing his disciples to be more productive. So far, he has three disciples: two females and one male.
The story doesn't dwell much on romance. Whether the female characters are into the MC or not is still up in the air. It is hinted that a member of his former guild, the Twilight Tea Party, had a thing for him. However, she hasn't gotten any screen time, and the romance has practically zero progress.
The translations are decent in quality but drop a bit in later chapters. Common issues include misgendering, inconsistent names (Reito, Ray, Rei), and duplicated paragraphs. Fortunately, it's not as bad as other series.
