Maybe more like 3.5 stars? Most of this book was about the relationship between two models, a newcomer named Aki (who I think was 21?) and the "older model" Tadashi who I think is 24, if I was getting the math and the ages right. A bigger age gap would've made more sense, but I might be wrong about that part anyway, since I found the timelines pretty confusing in several parts, especially the opening chapter.
It really seems like this was originally written as a one-shot that got expanded into four more installments, because so much got packed into the title chapter that I had trouble tracking what was supposed to be happening when. I liked the later pieces, though, especially when we got to see Tadashi actually working, and when the story was shown from Aki's point of view.
The spin-off chapter with the photographer and young model didn't really work for me; there were a few good elements, and I was glad that the model was the one who ultimately made the moves, while the photographer had been intended to keep everything strictly at work. I was getting flashbacks from the time I went to photoshoots with my roommate, who did part-time modeling and had gotten creeped on by her fair share of photographers.
There were still a few consent issues in this book - saying "no" and "stop" in the middle of sex, which was not then stopped, plus a first time where one party was very, very drunk and didn't remember much after. It wasn't enough to super bother me, but it did skirt the line a little.
There's one other story in here that's completely disconnected from the rest, and I actually found it...really fascinating. An openly gay guy comes home from university during summer break and sees his first love on the bus - the guy he'd never actually confessed to, because...he'd died on a scuba diving trip two years earlier.
It turns out the bus guy is actually the younger brother he'd known about and never met, who has a very similar appearance but a completely different personality. When they start up a relationship, which brother is he actually thinking about, and which is he in love with...?
It brings up a lot of really interesting thoughts, and I wouldn't have minded spending more time in that world, untangling those complicatins.
Hidaka's art is of course as pretty as always. Not my favorite of Hidaka's manga but still nice to add to the collection.
