Okamura trying his best after burning all the bridges, it's odd as he was the one who understood how relationships work by pushing Makoto to act like a boyfriend, but doing 180° whenever he had a chance...
Something tells me that the extra ingredients in that bath were aphrodisiacs and all that affection Kaori had to Andou was misguided, something like drinking alcohol...
"Prince of darkness", pfffffhahhahahhahahahhahahhahahahhahahahhahahaggagagaggagagaggagagaghahahahhahahhahahahhahahahhahah, well she is interested in the same thing as Andou so at least that checks out...
Glad it's not only his chuuni act that's not the only thing she was charmed...
Ouch, poor Okamura, although he did dig his own grave...
Maybe not fully dense, just that Andou is so not used to receive such affection, he doesn't take it seriously...
Got to appreciate Kaori braver and persistence, Andou just need to realize what precious gem he has.
