Those groping and kissing scenes didn't really need to be this long.
Yep, it didn't felt that long, nor that Yuzu was struggling much. It did feel intense and hot, though. I think the struggling part and the ominous music makes it a bit uncomfortable, that said Mei is imposing herself on Yuzu, so that's coherent.
I don't know if I'll like the changes the anime is bringing in. I don't mind additions, but changing big chunk of the story is a bit sad. Well, I guess after Made in Abyss and Girls Last Tour I should lower my expectations in term of fidelity for anime adaptations.
Another issue is Harumin's voice, I'd thought it to be lower, but other than that, it looks pretty nice!
