We finally find out whose underwear that was! Here's hoping for more nopan content!
I'm enjoying this game. You do a good job with the art and story. I love Suzu and Kana's expressions the most. They feel like expressions only they would give. Your strongest scenes remain those with many characters together, with background events and 3rd party reactions making me flip between pages to fully grab all the details. The sneaky conversations between Kana and Kogome are fun to notice, as are Suzu's occasional, subtle influences.
The "Actually I'm okay with being a harem" conversations are starting to feel kinda hard to believe with some of the girls. I believe it for Suzu and some of the more casual characters like Reina and Yukari. It just feels more inexplicable for Miko. Some of the other classmates don't currently feel like they would ascribe to that kind of relationship (though they obviously have not said anything about it yet.) I get that it's part of the fetish and probably has some secret magical rational in the story, but I need more doubt from the characters to buy-in to the idea. Surely a few of them besides Kana thinks it's a little weird. If I see more characters disliking the idea of a polyamorous relationship, only to become convinced of it, then I think I would find it more compelling.
Also, Ren's lived four months in as many days. This guy is going to go prematurely gray if you don't let him slow down. ^^ Even his relaxing trip to the beach had him running up and down the coast half a dozen times!
