Love Grown Cold

They've known each other their entire lives. But one thing after another years them apart. Will fate continue to bring them back together, or has their live grown cold?

This is a story about wha could have happened if Steve, Bucky, and Natasha had grown up together before finding themselves thrown into the modern world. There will be three main parts: them in the 1940s, Bucky and Natasha working in the Red Room, and finally post CACW period.
This will mainly be a Winter Widow story (some romance and a lot friendship) but there will be Stucky and Romanogers as friend ships.
This is my first story.
All characters belong to Marvel and my opinions are in no way canon.
