Short answer. Yes, and the right is treaty-based rather than a favour. Under Article 36 of the Vienna Convention on Consular Relations, which has been in force for Korea since 1977, if you are arrested, committed to prison, held in custody pending trial or detained in any other manner, and you ask for your consulate to be notified, the Korean authorities must notify it without delay. They must also inform you of that right without delay, and any message you send to your consulate must be forwarded without delay. What the consulate cannot do is act as your lawyer.
What the Convention says
Article 36(1)(a): consular officers are free to communicate with and have access to nationals of the sending State, and those nationals have the same freedom with respect to consular officers.
Article 36(1)(b): if a national of the sending State is arrested, committed to prison or to custody pending trial, or detained in any other manner, and that national requests it, the competent authorities of the receiving State must notify the consular post without delay. Any communication addressed to the consular post by the person detained must also be forwarded by those authorities without delay. The authorities must inform the person concerned of these rights without delay.
Article 36(1)(c): consular officers have the right to visit a national who is in prison, custody or detention, to converse and correspond with them and to arrange for their legal representation, and to visit a national serving a sentence in their district. They must refrain from acting where the national expressly opposes it.
Article 36(2): these rights are exercised in conformity with the laws of the receiving State, subject to the condition that those laws must enable full effect to be given to the purposes of the Article.
Vienna Convention on Consular Relations, Article 36. Multilateral treaty No. 594, in force for Korea from 6 April 1977.
What usually happens in practice
Notification is triggered by your request, so ask explicitly and ask early. The right to arrange legal representation in subparagraph (c) is the practically useful one for most people: consulates keep lists of lawyers and can contact your family, which matters when you cannot make arrangements yourself and the detention warrant timetable is measured in hours.
What a consulate will not do is defend the case, pay for a lawyer, translate your statement for the investigation, or intervene in the decision. Expecting any of that wastes the part of the process where time is genuinely short.
Consular visits and correspondence are also not confidential in the way communication with a lawyer is. Say what you need to arrange help; do not use the channel to discuss the facts of the allegation.
What you should do next
- Ask explicitly for your consulate to be notified. The duty is triggered by the request.
- Ask at the same time for a lawyer. The two requests are separate and both belong on the record.
- Use the consulate to reach family and to arrange representation, not to argue the case.
- Keep the facts of the allegation for your lawyer.
