Time Capsule

I was accepted into a college inside a city.

My friend of 2 years and I decided to make and bury time capsules underneath a big pine tree that was behind our high school.

We promised one another to dig them up when we married each other. Contents inside each of our time capsules were to be a secret until then, and if we didn't marry each other, the capsules wouldn't be dug up.

After 1 year, the girlfriend died in a car crash.

And 10 years after, I proposed to my college girlfriend.

I told everything about my past to my fiance, without hiding anything.

She said she'll be happy for both herself and the dead girlfriend, and wanted to dig up the time capsules. 

I refused, but the fiance insisted. I guess she felt some jealously towards the previous girlfriend.

After our wedding, we went back to my home town and dug up the time capsules.

In my time capsule, I had put in a scarf that the previous girlfriend had made me.

My fiance looked uncomfortable, but dug up the girlfriend's time capsule.

There was a small, dark thing the size of a fist.

After examining it further, it had small hands and legs and looked like it had a head of a human.
