shindou reads as ace in that he's wholly uninterested in sex (and at times, repulsed by it) while toshio is traumatized from repeated SA. they have a sexless relationship.

(ch 5-7) satoshi is ace and wants a platonic relationship, while kakeru is horny 24/7. satoshi is fine with having sex, but doesn't prefer it. he reads as a sex-indifferent ace.

ren is uninterested in many things, including sex, until he gets engaged to kaede and they develop a deep romantic connection. demisexual rights!

okay, hear me out. masaki uses sex and violence as a way to control/dominate others. he doesn't seem to derive sexual pleasure from his sadism and is able to have sex without hurting his partner. by the end, he's happy to engage in the kind of sex that tsubasa wants. there's an argument for aspec, sex-favourable masaki here.

this is a hot take but i'm pushing the mitsuhiko aspec agenda. he gets bored having sex with clients, and only seems interested and engaged when he's getting physical with sousuke. to me, it reads as a lack of sexual attraction, even when he is partaking in sex. my read is sex-favourable ace!

seiichiro is so impartial to the sexual aspect of his relationship with aresh that it reads as a general lack of sexual desire. he seems fine with participating in sexual activities, but doesn't think about sex outside of it. rather, he's more concerned about their intimate romantic connection. sex-indifferent ace, anyone?

haga is perceived as cold and unemotional. he accepts people who ask to date him and doesn't care about the break up. he only starts showing the desire to be close to another person when he develops a connection with tatsuo. even then, he struggles to differentiate between platonic and romantic attraction. pretty demiromantic, if you ask me!
