"We'll get married after I come back, so you have to wait for me..."
"I love you, Kira."
"I'll wait for you, Bucky. I'll always wait for you."
"But why... why haven't you come back? Where are you... my love, my Bucky..."
This is a Bucky romance, and the female lead doesn't transmigrate. The author doesn't think things through, so please ignore any possible plot holes. It starts with The Avengers. Thor will probably be the second male lead, since I don't really like Thor's original partner, Jane. When I went looking for Bucky/Original Female Character stories, I found pitifully few (there basically weren't any), so the female lead comes with her own plot-hole powers. Hahaha.
Come on, I must update it.
