OOOH BOY, Poe asking him about the costume after they are done and Ren suddenly blushes so Poe only understands and starts laughing. But not that mockery laugh but more like a happy one or something. And Ren blushes more.
Aww, yes.
During their first time, Poe was undressing him and thinking “what the kriff with these?” but also thinking it was kind of hot. He didn’t say anything afterwards, to high on satisfaction and happiness to say a word, he sleeps it down and time goes by until one day, while Ren is getting dressed in the morning and Poe walks to him to help him put on the suspenders, he asks what with them and Ren doesn’t give it much importance at first, he answer that this way he should not be worried about his pants getting off or something while on the move, that he thought it a reasonable way to keep them in place while designing the costume and Poe looks at him with wide open eyes: “You did this yourself?” “What?” “You designed the suit?” and Ren blushes, like all his face is red, and Poe knows the rest of his body is too because he has that adorable full body blush. And Poe laughs, and kisses him good morning because he just made his entire week with that, and Ren is just like ‘stop’.
