Having Yume be "the place that Hama returns to", equivalent to a home, a more certain and stable connection than even her own family, is yuri. It almost doesn't matter if they kiss or if they get married, these two have a stronger emotional bond with each other than with anyone else, and it is that bond which saves Hama here.
By the way, what happened to all of the previous Ura Baito chapters? I can only see the ones from 193 onwards, did the rest get taken down by copyright claim or something?
