Katniss Everdeen and Peeta Mellark, married now but once it wasn't as easy. Peeta Mellark and Gale Hawthorne fought over her through High School and into college, in the end Peeta Mellark, Her Dandelion in the Spring, ruled out.
It was more than just silly games between the two of them though Gale Hawthorne gave Peeta his fair share of black eyes and broken bones in his attempt for Katniss' heart, the thing that broke the camels back though was when he crashed Katniss and Peetas Wedding. Because of that and Katniss' stubbornness, she could never forgive Gale.
When Gale did get married he never apologized for what he did, as a result if Peeta could ever convince Katniss to have kids they could not have ANYTHING to do with the Hawthornes. Katniss and Peeta eventually did have two kids, first a girl named Meadow then a year later a boy named Tiryel [ty-rell] but shortened to Rye. 5 years later Peeta convinced Katniss to have twins Lily and James (after Katniss' father). Gale and Andera however had 3 kids the about the same time Meadow and Tiryel were born, their names are (oldest to youngest) Liam, Amber, and Jade. [boy, girl, girl]. Andrea and Gale wanted nothing to do with the Mellarks and the Mellarks wanted nothing to do with them.
