I like Kume providing no explanation when asked why, because really they're the least sex friends out of them all, she only messes with him to harass Agawa, lmao.
I hope the next chapter is something funny and character based.
And shout out to Akito for kind of setting a boundary, it makes sense for her to do that, since realistically, she's been presented as not thrilled about the sex friends situation multiple times, even though she also obviously likes sex with Gotou, so it's cool for a character to take that perspective at all in this goofy ass story (who knows if it will be long lasting, I hope it will)
