you can do this
\startMPpage[offset=2mm, stacking={1,2,3,4}]
boxit.A("\boxframed{Box A}");
boxit.B("\boxframed{Box B}");
boxit.C("\boxframed{Box C}");
defaultdx := 0pt;
defaultdy := 0pt;
A.c = origin;
B.w - A.e = (1cm, 0);
0.5[ A.s, B.s ] - C.n = (0, 1cm);
draw image (drawunboxed(A,B,C)) withstacking 2;
drawarrow A.s +- C.w withstacking 3 ;
drawarrow B.s +- C.e withstacking 4 ;
newpath highlight;
highlight := (A.sw -- B.se -- B.ne -- A.nw) enlarged EmWidth;
fill highlight withcolor "darkgray" withstacking 1;
\stopMPpage
