Exactly how steamy is this story?

Surprise: Pygmalion's got a lot more violence than romance. Higgins and Eliza come closer to killing each other than loving each other, and pretty much everyone's terminally single. Mrs. Eynsford Hill and Mrs. Higgins must have been married at some point, but we don't hear anything about their spouses. Pickering and Higgins are confirmed bachelors.
Sure, Freddy's crushing pretty hard on Eliza, but Eliza doesn't seem all that interested in him (except when she's trying to annoy Higgins).
In the end, Alfred Doolittle's pretty much the only one who even comes close to getting any lovin'. He certainly seems to like getting married, anyway.
