The music taste is terrible. I always look forward to this series, but I simply cannot accept the taste in BGM. Please change it to music with a better beat that gets you more pumped up. For example, I think it would be a good idea to reference the fast-paced, energetic songs used in Chinese strip-style videos. If you commissioned music students to compose that kind of track, you could probably produce high-quality work without spending too much. I sincerely hope you'll consider making this improvement.
"Fully exposed is not erotic." It's not that high exposure is necessarily better; rather, the true appeal is brought out when wearing underwear. It's precisely because of the underwear that each pose and act stands out, stimulating the imagination and making it feel more erotic.
