Heart to Heart Romance Library #206 features the story 3 Loves Have 1, which was originally published in Charlton's Secret Romance #20. This is one of those utterly implausible romance stories in which both the guy and the girl act like dicks but true love wins in the end, so you know they truly deserve one another. It also has the distinction of being selected for an issue of IDW's Weird Love series.
This is also the highest numbered issue of the series I have seen, so it may be the final issue in the series. Maybe the Murray editors read the story and figured enough is enough. Maybe that's why the original owner of this copy defaced the characters on the cover. And maybe I hope there is a Heart to Heart Romance Library #207 for the sheer heck of it.
