BI4JKY Ugh, the friendly media outlet that initially initiated the lawsuit has already dropped it. I plan to wait until after my postgraduate re-examination (also a law master's program) before dealing with this matter and restart the legal process.
While I also... according to the law school textbook, it's a breach of contract. However, that friend from another university said they were a lawyer, so I thought there might be other possibilities.
Later, I checked the lawyer's professional disclosure platform, but I couldn't find any information about that colleague. While it was good to be helpful, one shouldn't falsely claim to be a lawyer.
