Hmm I am kinda wondering if what Ayaka-san is feeling is really attraction towards Aki, or just want to bond(as in, be a "family") so to speak. Like, this chapter clearly shows there is some sort of connection, but not sure what type of feelings are floating in there. Like, the other girls(the shotacons) are infatuated with Aki cuz he is a young kid, but idk what is Ayaka-san's case. Either way, this chapter shows the major progress that Aki has gone through, homeboy is really becoming a man! lol
