This feels very forced, but also so much more tame than other "my profession was considered terrible until I figured out it was good" mangas... I'm used to everyone turning on the MC, or some particular antagonist orchestrating the MC's downfall after finally getting an edge (like having some superior skill). Whereas here it seems that only the author is against the MC due to how the setting seems to be designed terribly while everyone still seems to like the MC.
His engagement is canceled on account of his weird skill, but it isn't like everyone gets immediately toxic and elitist about it. The former fiancé seems regretful, and like it is the church forcing her. Nothing like the fiancé immediately jumping ship to some antagonist that has the "hero" skill and saying she never loved him. And I'm willing to forgive a lot of people about this since the law requires that he works in a profession related to his skill, so people with sucky skills have to work in sucky professions even if it's against their will, apparently even if they could have been usefully employed in a different profession. Would you want to marry someone who has been forced by the law to have to work in some terrible job and be miserable for the rest of their life?
Firing the MC wasn't enough to make him a wooby, and it was an actually reasonable reason like having an extremely niche skill that isn't that useful in a general practice. The only part that was weird was that he got hired in the first place, with the author having to invent a special law that forces people to work in professions related to their skills and that those places have to hire him... But then that would give the MC job security and we can't have that, so the law apparently doesn't prevent the job from firing him later.
Now the author checks his watch (haha...) and realizes he still hasn't figured out a way to get the MC to figure out his skills... Uh... Let's also pin a crime on him. And that crime isn't one pinned on him by someone that hates him / hates clockmakers, it's just a random criminal that noticed the MC's hot friend and the MC is in the way. Oh, right, the MC apparently has a hot friend that is nice to him. She totally wasn't invented just now just so the criminal had a reason to mess with the MC...
Edit: oh, nevermind, it seems like the author completely switches personalities in the next chapter after and starts to really turn the world against the MC. How dare I judge the author's style from just one chapter...
