A lingering scent that invokes familiarity

Scientific research reports that we are attracted to people who have opposing MHC (Major histocompatibility complex) from us. This is to ensure a diverse immune system of the offspring and increased chances of survival under difficult conditions (disease from infections). However, they said that good friends who have similar MHCs tend to have a better connection but this is not for the sake of breeding.

Why does your scent triggers a memory, a familiarity, a comfort and a sense of lost love.

It started from the first day and still did not dissapate.

I know this from the blanket we used to share. How can the scent from two individuals be so similar? Is it the laundry detergent, or just the scent from back home that I miss?

If I could fill a jar of this scent, I would give to possess it.

I crave for the oxytoxins and endorphins that your scent induces in my brain.

I have to separate the individual from the scent that I love, before it swallows me up whole and I cannot withhold.

Maybe it is my scent, not yours that I love. If we have the same scent, then I might be narcissistic.
