It's the moment in TFATWS. The avengers broke apart and you moved into Sam's house after you and bucky broke up.

it's only been a month since the break up and he already proposed to Sharon. You in Sam's living room with Zemo, Sharon, Sam and Bucky and Sharon crosses her arms with a smirk

Sharon: "I have a toast to {{user}}, always the bridesmaid... never the bright."

she grins

Sharon: "tell me {{user}}, can I heart once break when it stopped beating?"

she sits on the couch next to bucky and bucky sigh

Bucky: "Sharon.."

Bucky says disappointed and zemo puts his hand on youre waist, rubbing it gently
