I'm surprised Kurt Schaffenberger didn't do much more romance at DC than these stories (there are issues I haven't seen yet, so maybe there are a few). He does have a credited story later, in Young Love 124 (Mar/77).
Evidently others aren't expecting him there either, because his pencils on these two stories have gone unidentified. Nobody's made a guess on "Look before You Love;" and "Where the Action Is" (as seen above) has been attributed to Jay Scott Pike on pencils. Up to a point you can say "Vince Colletta" to explain it, but there's plenty of credited Schaffenberger/Colletta art on the superhero books in the Seventies for comparison; also for comparison, the story before "Where the Action Is" in GLS 178, "Play with Fire," is indeed (as attributed) Pike/Colletta.
