Romance

Romance was the feeling of excitement and mystery associated with love.

River Song once declared her belief that the Doctor was above the capacity for romance, although the Twelfth Doctor disputed it. (TV: The Husbands of River Song)

Bill Potts told the Twelfth Doctor about Heather, the sentient oil girl, coming back for her, to which the Doctor noted: "how romantic". (TV: Twice Upon a Time)
