Well the clothes are wet they need to dry, and the two of them will need to keep warm in the meantime through some totally platonic not-at-all yuri full body skincontact.
When the moment arises, they're always protecting each other. Now they've got some bonding time and still have to somehow win the race. It's nice seeing them reconnect even without knowing who they really are. Their connection to one another lasts no matter what. They're literally positioned as enemies in this world and still can't help but gravitate to one another. That's part of what makes it so nice.
Nice double save, into drying clothes, into keeping each other warm, into skin-to-skin bonding, into big yuri time.
Grandpa is actually the best wingman.
Thanks for the chapter!
