I'll be honest, after this chapter with how Yoru was proven to genuinely love Denji, now if next chapter he chooses her over Asa, that will be totally understandable and we shouldn't criticize him for that imo.
For real tho, why should he choose Asa at this point? Yes she cares for Denji, but Yoru loves him too and gave him a lot more fun than Asa ever did...Speaking as an Asafag here
