If Chisa's reaction to going to Okinawa together with Iori just the two of them isn't confirmation that she actually likes him then I don't know what is. This further leads me to believe she wasn't being truthful during the lie detector game. I hope there's some good development between the two during their trip there.
Also, I don't really feel sorry for Cakey. She's too timid and hasn't confessed despite liking Iori for...how many chapters now? She better not ruin this (or any of the others for that matter) or I'll dislike her even more than I already do.
