I like this movie a lot, even though I'm not wild about the ending.

I think it is an excellent piece of queer cinema, although not necessarily BL. It doesn't use any of the tropes, archetypes or narrative beats I would expect from the genre.

I would recommended it as queer cinema. Beautifully filmed and acted, thoughtful and thought provoking. Although it is more likely to make you cry than smile.

It's one of Taiwan's few queer film pieces of this type, and stylistically it owes a lot to early Japanese queer cinema. Which, in turn makes me think of the new Japanese stuff we've been getting that harkens to those roots like Restart After Come Back Home or His the movie, but less cerebral as it has Taiwan's signature excellent chemistry and visceral passion.

Your Name owes a lot to its sibling source (?) project 2017's Red Balloon. So If you enjoyed YNEH then you should track that one down, it shares a main actor. You'll probably find it worth watching. Korea's Just Friends? also tackles enlistment but is way more BL.

I feel like if you're a big fan of YNEH then you probably also enjoyed (or would enjoy)
