To add: Roommates of Poongduck 304 (2022)
Personally, I would add the *hinted at to Love in Spring and Color Rush 2 (which you already have listed). Though this is just my personal opinion, so maybe others disagree. Both lack the Gay Romance tag, and do not have any gay relationships in them. Both do however have the Slight Romance tag, but the Bromance tags are higher up on the tag list for relevance.
Also, not added: Color Rush 2 (Movie) (2022)
