Domeyashiro, my fellow yaoi and Yoneda Kou lover, who speaks Japanese, from Saezuru fandom in Tumblr identified other 2 tracks and gives more information, also about how to buy the CD - https://domeyashiro.tumblr.com/post/156077645438/%E5%9B%80%E3%82%8B%E9%B3%A5%E3%81%AF%E7%BE%BD%E3%81%B0%E3%81%9F%E3%81%8B%E3%81%AA%E3%81%844%E5%B7%BB%E7%99%BA%E5%A3%B2%E4%B8%AD-on-twitter
There are three samples. The 1st one is from ch 17 p 2-6. I held my breath. WAAHHH...
The second sample on the link that you posted is from chapter 18, I think. Does anyone know if I'm right? Thank you so much for the samples!!!
Sorry! I didn't read all of @anonymousone message, so I missed that you'd already noted that it was from chapter 18. And the third sample is from pages 15 to 19, chapter 19.
Thanks a lot, ikariam1!
