In the world of Doraemon, the love story between Shizuka and Nobita has long been seen by fans as destined. Fujiko F. Fujio, the creator, has often hinted that the couple would eventually marry. However, whether they truly live happily ever after and grow old together has never been addressed. Recently, a dedicated Doraemon fan proposed a deeply emotional theory about Shizuka and Nobita’s fate 45 years later, based on dialogue from the Later chapter of Doraemon Plus.

Shizuka and Nobita’s Unfinished Ending
According to this theory, Shizuka does become Nobita’s wife and they have a son together. However, Shizuka passes away before Nobita and doesn’t live to see their son’s wedding. Fans point to dialogue in chapter 5 of Doraemon Plus, where an adult Nobita recalls and talks with his younger self and young Shizuka, revealing details about their son Nobisuke’s future.
In the story, adult Nobita swaps bodies with his younger self, allowing him to revisit his childhood. When he meets young Shizuka, his close friend and future wife, Nobita can’t hide his emotion. The future Nobita shares stories about their son growing up, getting married, and even honeymooning on the moon. These moments make fans wonder if Shizuka were still alive and by Nobita’s side, would he be so emotional?

Heartbreaking Clues from Small Details
Fans analyze that adult Nobita’s intense emotion is usually seen when someone hasn’t met a loved one for a long time. This suggests that 45 years later, Shizuka and Nobita might no longer be together. Some speculate they could have divorced, but others argue that if it were a simple divorce, adult Nobita wouldn’t recount his son’s life in such detail.
Logically, a living mother who remains close would surely know how her son grew up, got married, and went on his honeymoon. Therefore, the most reasonable explanation for Nobita’s reaction is that Shizuka passed away earlier, which is why he is so moved when meeting his wife’s younger self. This also explains why she never witnessed their son growing up and starting a family.
Although this theory is compelling, Fujiko F. Fujio has never officially confirmed any details about Shizuka and Nobita’s life 45 years later. So, this remains a fan perspective, a bittersweet yet touching speculation about the childhood couple we all cherished.
