Was thinking the same thing, he he just told Karino he gave up and didn't care anymore what he did to him, that would really unsettle Karino. But Azusa is stupid proud, that ain't happening.
i was thinking about the specific scene where Karino goes in and ask if Azusa's been meeting other guys, and I feel like there's some jealousy going on there.
If Azusa said sth like, "Yeah, what's it to you?" HO MY GOSH THAT WILL BRING RAIN TO THE HEAVENS BECAUSE KARINO AIN'T GONNA TAKE THAT SHIT
plus, i think his only two "weaknesses" is himself [duh] and his half-brother, because a love affair scandal could really ruin his future (=・ω・=)
idk bout yall but i think azusa is trying to hard to get back at karino i mean if he just act disinterested towards karino about everything even during sex i bet that would rile karino up or yknow get karino to be jealous or smthg
