If I go crazy, then will you still call me Superman? (слэш)

While recovering and reconnecting at Tony and Loki's cabin, Bucky settles into a routine and family feeling he never thought could be his. He and Steve have rekindled their relationship that was cut short in Wakanda at the Snap, but now he knows that their time together could be cut short again when Steve returns the stones to their rightful times and places. Bucky is well-aware that Steve has to return one right back to the S.H.I.E.L.D. base where Peggy Carter is in charge. What will that mean for them? Will Steve come back or will he stay to get that dance with his best girl?
