Veronica Lodge and Betty Cooper were high school sweethearts. Cheryl Blossom and Toni Topaz were the "it" couple. Everyone believed that they were going to get married, adopt kids, and grow old together. Everything was good before Cheryl caught "the girl next door" with "the serpent beauty" at Veronica's graduation party. They were naked on a bed, asleep, cuddling. Cheryl and Veronica were heartbroken and left town that night without telling anyone but their parents.
