I wonder if we'll ever get Kiyo's perspective on this love triangle situation. She's Sumire's best friend and they're around each other a lot, so I think there's a good chance she's figured out how Sumire feels about Kenta, but I don't think Kiyo's aware of Kenta's feelings. I would not be at...
this age gap between the MC and the likely ML is pretty unpleasant, 5 years would no big deal if they were both adults but they ain't, ML's 15 and already seems like he's attracted to the 10 year old protagonist
These are all pretty good! They're more 'loosely inspired by ballet stories' than 'japanese adaptations of ballets', so if you're a fan of the original stories don't expect these to be especially similar.
Not great. The age gap's uncomfortable to say the least. The main character's fairly entertaining but honestly asides from her the rest of the named characters are just kind of annoying.
