Puzzle 242: Sandwich Tapa

Another new tapa variation.I am sure this is the inverse of Not alone tapa.Do comment if you think I am wrong.This one is almost symmetric.

Rules: Standard tapa rules.In addition to that, all circles indicate that the cells containingg them are sandwiced between atleast one pair of oppositely shaded cells(they are sandwiched horizontally or/and vertically). Whenever you see a circle along the edge of the grid, assume that you still need to shade/unshade two cells to form a valid pair around the clue.
