Repeated Neigbhours Sudoku (Fun With Sudoku #129)

When I first time created the Repeated Neighbors Sudoku puzzle, I had a tough time checking the converse rule is followed in the image and I have to check many times that I did not miss graying out a cell. However recently I wrote a program to generate the image for this Sudoku type. Now, this program will automatically take care of the converse rule. I have created few puzzles of Repeated Neighbors Sudoku type after generating images from that program. I have posted most of these puzzles and will create some more puzzles of this type soon.

I am posting this Repeated Neighbors Sudoku as 129th Sudoku in the Fun With Sudoku Series. Can you solve this medium-level Sudoku puzzle?
