The seme is drunk while the uke had control, so that instance whether the seme liked it or not, and consented, that consent doesn't count as valid. The point that they fuck the next morning doesn't really matter because if it does that mean that the seme didn't rape the uke during their first drunk sex since they had sex again? No, it doesn't cancel that rape happened.
And the uke basically raped the seme when he had sex with him when the seme is drunk.

When the seme raped the uke (drunk sex) everyone hated the seme, but now that it is the uke that raped the seme (2nd drunk sex) , people dismissed it as simply "hot".
