Looking at You (слэш)

Bucky doesn't understand why no one ever says anything about Tony's PTSD.
A year after they have all come back, after they all hugged and made up, Tony is still jumping anytime someone speaks to him. His hands shake when Steve raises his voice. All he does is work and drink and apologize for being around.
And nobody notices except Bucky, because he is looking. Constantly. Watching Tony as he goes through his day to day.
Bucky looks and LOOKS, until he is having a hard time even wanting to look away from short spiky hair that begs to be mussed, deep brown eyes that always looks so sad, and perfect lips that Bucky just wants to kiss forever.
Bucky looks for so long that now all he wants to do is touch and hold and fix everything. But Tony can barely be in the same room as Bucky, cant even look him in the eye.
So Bucky doesn't know what to do about Tony, but he is determined to do something.
Because all he wants is to look at Tony, and see Tony looking back with a smile.
