It was very Japanese BL of At 25:00, in Akasaka to make Shirasaki excuse Asami's behavior believing that Asami was cuddling him as a placeholder for his dog.
Only for Asami to hold Shirasaki tighter and tell him that he could smell him.
That wasn't just a "no, you're wrong" but a "I'm very aware that it's you I'm holding because I'm actively holding you so tightly that I can smell the shampoo in your hair which I just blow-dried and the lingering smell of the food I just made you and the soap you used on the nape of your neck and . . . "
Japanese BLs are always going to reinforce that man is of sound body and mind when he is making a move on another man.
