I just wanted to point out, reading the first few reviews, that I used a YouTube video of Yan-chan's voice as a reference and in the video she describes, in a monotone voice, that "For as long as I can remember, I've never been able to feel emotions". I can tell you I definitely was in to this recording and I enjoyed it very much but the lack of emotion is due to character description and reference, if this is not Yan-chan's true persona then I apologise for not voicing it correctly. The echoing voice over the moans are also Yan-chan's thoughts, not her actually speaking.
I'm sorry to read that some of you so far think it's awful, but I understand everyone's opinion differs! I hope that I at least got slightly close to Yan-chan's voice based on the reference I was given!
