I always been a sucker for RoCH (I absolutely dislike the prequel LoCH).
I'm hearing this movie was aired on Feb. 1, 2024. So far I found absolutely no info on this movie.
MyDramaList doesn't even have an entry for this title!
This is the Douban page for it:

The only places even talking about this movie are on Douban and Soompi forums.
