I don't have an idea how weird Japanese comedy is but this is certainly part of that humor they have. It's so embarrassing to read because we didn't get anything other than a full fan service and two perverted housemates. Reiji really pisses me off everytime he makes such chapters where he makes Kazuya a total creep. This cycle happens since 2017. I guess we can call this one a padding to fill another manga volume but damn Reiji needs to step up and make sensible chapters because honestly their story is way overdue. I'm already starting to take consider your other commenter's ridiculous dark theory about the manga of shaking the pairings. Other note: This is an absolute retcon of the manga where since from the beginning Chizuru doesn't have that mole between her thighs. We already saw her in her bikinis and this ain't the first time we saw her wearing that pajama shorts from Sumi but hey there's no mole at all. Random not fun fact this is the 100th chapter after that gore chapter 218 where that mf Umi got an imaginary "win".
Reiji is trolling us. He's probably cackling right now. Also, I didn't even think about how we/Kazuya have seen Chizuru in a bikini, so that mole makes no sense.
@@Lolobugga1 sensei's really getting out of touch in his story telling. I felt bad for Chizuru despite of I don't like her attitude in this chapter where again she became a sexual subject. Just like how Reiji captioned his old tweets about Chizuru sexualizing her.
