Nice.Hope this gets an English translation later. Also, there is another work of Summer's that is a Soapland theme and it hard-focused on Honolulu 4 1/2 years ago. The C96 doujin (which was cosigned to C97 for some reason) was never uploaded anywhere and it's not even in Summer's official melonbooks page.
In case you are wondering what it is, here is the link to its preview on pixiv: https://www.pixiv.net/en/artworks/76205524 Twitter post: https://twitter.com/sama_samasa/status/1160547630277021696
Apparently, it was only sold at the venue. Godspeed to those who intend to get a copy.
