Takes place in Earth-616.
After defeating Electro, Peter Parker returns home, to find Mary Jane in the process of moving in. Mary Jane leaves for a photo shoot, leaving Peter to ponder how he will be able to provide for both him and Mary Jane.
Peter takes his photos of Spider-Man defeating Electro to the Daily Bugle and is surprised by the staff with a party in honor of his upcoming wedding to Mary Jane. J. Jonah Jameson arrives, clearly irritated, and starts to complain about why they are hosting a party when they are supposed to be working.
Peter is barely able to sleep that night, thinking about his impending wedding. The next day he meets Mary Jane. He leaps to the ceiling and goes down to one knee, asking her to marry him once again. "I hate cleaning footprints off the ceiling," she responds with a smile. They both eat, but can't help shake their worries about the wedding. Mary Jane leaves for a meeting, where her old boyfriend presents her with two tickets to Paris, that she can only take if she skips the wedding. Peter goes to Aunt May's house, and goes through a scrap book, remembering his most prominent times with Mary Jane. Mary Jane and her aunt arrive, and they announce the upcoming marriage to their family. She leaves in a Ferrari with her ex-boyfriend, and Peter takes the subway home. Both are starting to have second thoughts about their marriage. When they meet up again that night, Spider-Man takes Mary Jane out web-slinging to clear their heads.
The next day, Peter's best man, Flash Thompson, and his best friend, Harry Osborn, take Peter out for a bachelor party, but he's beginning to show his true feelings about the wedding. They try to convince him that love conquers all. Meanwhile, Mary Jane is having a grand party across town. Peter finally decides to go home for the night, and has nightmares about all of his enemies trying to attack MJ, and being helpless to stop them. He wakes up in a sweat, wondering what he should do. Meanwhile, MJ is out with Liz Allan, wondering the same.
Later at City Hall, all of the guests are in attendance, but both Peter and Mary Jane are late, leaving everyone confused. At the last minute, they both appear and are married by Mary Jane's uncle, judge Spenser Watson. MJ gives Peter the tickets to France with which her ex-boyfriend tried to tempt her, and they go off on their honeymoon to begin their new life together, as Mr. and Mrs. Parker.
