So at the end the seme says “you are under the control of man that you don’t even know” implying that what the uke said, how he’s so manly and perfect, isn’t accurate cause the uke doesn’t know who he actually is. The uke then replies that what he sees is the truth. So basically whatever past the seme had or who he was in the past doesn’t matter to the uke, only what he witness now is what matters. So now your question. The uke says “I will accept anything you give me” meaning he will accept all parts of the seme, even the parts that he doesn’t know, ie the insecurities the seme has, because to the uke every part is perfect even the ugly parts too. Why he said it? Well I think it is to ease the seme’s inner conflict that is explored in the prequel. Hopefully this helped.
i kinda didn't get the last part. what does it mean if chousan give it i will accept it?
