This is a bit odd. We could always tell this serie was revolving around a siscon and an age-gap relationship, and I was fine with both these thing. Such stories can be great!
But this chapter and the previous one pretty much acknowledge how creepy, and frankly a bit disgusting (if this were to happen in real life, all is fine in fiction), the relationship between these characters are. To the point that I can't really root for kasane and Meguru anymore...
Guess I'm on team childhood friend from now on. Thank you for the translation!
