this had the same vibe, of the 2nd season. reading the description was sure this was a retelling of the plot, with a happily ever after ending (as don't think, there will be a season 3 or another movie).
but it wasn't a retelling (+ summarization) of the BL series. one could just watch this movie & get a general background to how everything started (went on in the series), & considering the 1st season, it would save them a lot of headache lol (well i was the only one having a bad trip??) if u know u know. ?

(pretty sure) was the odd one out, cause the 1st thing i did was search if Kazuki was in the character list. he's a side-character that has almost no screen time & yet he has always been my favorite (think mainly cause of how everyone kept bad-mouthing a pretty sane/normal/healthy in the head character) ??
also noticed Shitara & Anna; the sec saw them, was sure (what i thought would happen in season 2) would occur here. kinda hard not to come to that conclusions, as Shitara came off as even crazier then Hira (& that's saying something, dude obsessively addicted to Kiyoi).

having watched this, wont say this was perfect or loved every sec. it was good (for sure enjoyed it more then the 1st season) & thankful that now that we get Kiyoi's POV, it doesn't feel one-sided. where Hira is the subservient, pushover that's being taken advantage off & gaslit. like in season 2, u see that Kiyoi's as addicted & his attitude, actions in the 1st season stemmed from his insecurities. that he as addicted to Hira as Hira is to him. so putting the "drama" of the kidnapping aside the plot was cute & they both finally (in their own way) committed to each other.... "and they lived happily ever after".??
