In BDSM relationships they often have safe words because no and stop don’t always particularly mean no. The Uke wasn’t fighting him off, he was just embarrassed and said ‘no’. The uke is completely capable of head butting the shit out of the seme to get him to stop if he actually wanted him to stop LOL

i'd also like to add that although no means no (as i am a firm believer of this and do not condone rape), in asian culture especially japanese/korean, it is common to say no even though one may want something. often times you'll see them being humble, for example if you give someone a gift/etc, they will often say no even though they might actually want it bc it may be seen as shameful/selfish (this applies to sex as well). i personally think this is one of those scenes where the uke doesn't actually mean it when he says no/stop
To many occasions he told him to stop, and this nigga just kept going...tf. the whole puppy stuff is making cringe and honestly is just getting weird.
