Back to the 1980s With My Childhood Sweetheart, and Straight to the Marriage Bureau

Two people who fell in love in the twenty-first century regretted never getting married. But after discovering that they had both transmigrated to the 1980s, they wasted no time getting their marriage certificate.

But getting married wasn't their only reason for coming to the 1980s. They also wanted to defy fate and change their lives.

They had to change the fate of the original bodies they had transmigrated into, as well as their own and their parents' fates. They even planned to become friends with their parents while changing their lives, and maybe get their parents to call them Big Brother and Big Sister! Just thinking about it was fun.

But later, they discovered that they weren't the only ones who had transmigrated.
