I'm a bit confused on what the に particle is doing here in this sentence, まじめに
して下さい. I know that the sentence means, "Please take this seriously" but I'm
not sure why に is used here. I've seen it used most often as a time or target
marker but I'm not sure what it is doing here nor can I think of another
particle that would be better used here. If anyone could let me know its usage
in this scenario, I'd really appreciate it.

Thanks

What is に 's purpose in まじめに して下さい?
～にする is an extremely common grammar structure that indicates decision. Check
out [this page](https://japanesemeow.com/japanese-grammar-lessons/to-become-
and-to-decide-on-ni-naru-and-ni-suru/) for an in-depth description of how the
grammar works.

Basically ～にする indicates that the subject makes a decision to do whatever
comes before the に, where in the case of this sentence, it is まじめ. As such,
the following linear translation from Japanese to English may sound clunky:

> Please decide to be serious.

You will commonly see a similar grammar point ～になる, which is very much the
same. The difference, is that some party outside of the subject is making the
decision. You will find information about this grammar principle in the same
link above.
