Cold Nights in Octo Valley

Winter is slowly creeping into Octo Valley and Cap'n Cuttlefish is out of blankets, thanks to his affinity for plush making.
His prisoner proposes an unusual way of keeping warm for the night, that may or may not re-egnite a long lost spark in both of them, as they keep getting closer and closer during the following winters. Can the cold help mend the wounds on their hearts, that have been inflicted by the war?
