Disclaimer: The uke a virgin seems like demisexual inclined towards guys.
Disclaimer: In this case, it is hinted that the seme sleeps with both sexes. Then, the uke affirms he is gay.
Disclaimer: For me, the seme is bisexual. Even though he likes guys, he is fine with women I think so. For uke, so far his current romantic and interest is toward a man.
Disclaimer: Seme is bisexual since he has a female lover before, and also he has having sex with the uke as 'sex worker' which shows he swings both ways. For uke, he seems pure but his supposedly next romantic interest is also a man.
Disclaimer: For seme's case throughout the series, I am not sure whether he is bisexual, queer, gay, demisexual or straight because of some confusing details about him. However, I will just use one detail which says that cute Japanese boys is his type. However, a side character said he went only with women. So, I imply that he is bisexual. For uke's case, no doubt he is gay.
