thank u and ily for asking this. no worries english is not my first language too. here’s some comics i like with them in it, but i have to warn you beforehand, their story is not silky smooth. 1. black widow : the name of the rose (2010) 2. captain america & bucky (2011) 3. winter soldier (2012) 4. black widow (2014) 5. black widow (2016) if u have time i also recommend that captain america (2005) run until bucky stopped being cap because it has a lot of buckynat in it. if you have a hard time searching the comics u can always ask me on dm. i’ll drop a link below for the more detailed buckynat guide.
