What the fuck is actually going on. Why is everybody screaming het?
Aware that Asuka is not interested in him
"Just forget all about it"
"I don't have any weird expectations to begin with"
"I don't want to force my feelings on you"
Isn't this basically Jun's way of saying he's given up on Asuka?
In fact, with Asuka telling Jun of her incest gayness this is basically setting up for Jun probably helping out Asuka with advice or something. At the start of this chapter Asuka was kinda forcing Ayako to tongue kiss so the focus would probably be the "I don't want to force my feelings on you" part.
Here's what I think will happen. With some advice from Jun Asuka will be less pushy and forcing in kissing Ayako because Asuka will think stuff like "I don't want to force my mom to do stuff she doesn't wan't to" and stuff and it'll make her less initiative in this whole relationship with Ayako. At first Ayako will be glad that Asuka is less pushy but then starting to fell empty, like she'll expect Asuka to kiss her but she won't and Ayako will start thinking "why isn't she kissing me?" and "i-it's not like I want to kiss my daughter, what is wrong with me?" and eventually it'll lead to "I won't lie to my feeling anymore, I WANNA KISS HER" and this set's up for Ayako to be more active in the relationship instead of the current relationship of Ayako only doing whatever Asuka asks for.
Also as some other has said I also don't think there'll be any misunderstanding from Ayako looking at Jun, or if there is she'll simply talk about it and it'll be solved without drama. This author has done the 'drama foreshadowing' thing at the end of a chapter multiple times and it was all a bait and there's barely any angst or drama at all (as seen by Akira chapters). This is probably another dramabait and I'm not biting it again for the third time.
