Bucky is in love with Sam, but Sam is in love with Steve, and jealous of the relationship he has with Bucky. When Steve moves away, he encourages his two friends to get to know each other better. LOTR marathons and gay panic ensues. I loved the humour in this fic, and their relationship is very lovely!

Clint offers his flat as a safe spot to regularly crash in, and Bucky gladly takes the offer, but only when Clint is absent or asleep... until Clint brings home an abandoned kitten and Bucky falls in love with her!
This was so soft and lovely! Slowish burn with mutual pining, lots of pets parenting, and Bucky discovering he is still capable of love... Amazing!
