Pre-TBBT timeline where Sheldon and Amy had a pact to marry one another when they're still single by the age of 40.
The mutual understanding and acknowledgement was reciprocated between the two.
Having met back on their college days, they became friendsã…¡ colleagues, they insist. They kept a long distance friendship of keeping tabs to another. It's just two scientists communicating to and fro. The two of them were on the same caliber, having endless discussions on any topic they can think of.
They've even made a marriage pact, because they love preparing for everything. Of course. Eventually, life got on the way and the cherished friendship of the two were left as is.
It was both to their surprise when they matched on a dating site years later.
Sheldon later thanked Howard and Raj on their insistence to go on the date.
A/N: I was thinking they had a more smooth sailing relationship because they knew of each other. If found a story with similar plot or based a story from this prompt— I'm shamyshenanigan on IG! I'd love to read the story.
