(CNN) -- "Jughead, do you want to be my best man?" comic book character Archie asks on his blog.
The marriage issue is due to arrive at comic stores in August and on newsstands in September.
Archie Andrews -- who spent decades in high school, flirting with girl-next-door Betty Cooper and heiress-next-door Veronica Lodge -- is getting married.
"I am so excited, I am getting Married to Archie. There is so much to do, so many plans to make. I wonder if Betty wants to be my Maid of Honor? I bet she is so happy for me!" Veronica writes on her blog.
Yup, Archie is marrying Veronica, breaking Betty's heart.
"I am so sad, I don't even know what to say," Betty writes on her blog.
Betty has months to dry her tears. The marriage issue is due to arrive at comic stores in August and on newsstands in September, according to publisher Archie Comic Publications (archiecomics.com).
"It's the milestone 600th issue and we're serving up the Archie story of the century as Archie marries Veronica!!!" the publisher says on its Web site.
"The 32-page issue takes a look at Archie and his friends after they graduate college! What careers will they seek? Will the friends stay in Riverdale or disperse? What would lead Archie to have marriage on his mind? And who would he choose Veronica or Betty? How will Betty react? How will Veronica react? Can Archie shake off his klutzy past and hold down a steady job... for more than a month? One thing is certain: this will be the biggest Archie Comics story ever!"
Archie might be in over his head. According to Veronica's online profile, "She is very conceited, usually fickle, and extremely flirtatious."
He went for the bad girl instead of Betty. Her online profile says, "Through every crazy, loving scheme to win Archie's love, Betty always remains completely unaffected, loyal and sweet."
Maybe Archie will come to his senses. His online profile says, "He does things on the spur of the moment, which almost always gives him a very keen cause for regret."
