Twin Givens Sudoku (Fun With Sudoku #155)

Twin Givens Sudoku is an accidental creation where I wanted to create any other Sudoku which I have not come across earlier. I could not implement the given rules for that Sudoku properly and come up with this Sudoku type. The name Twin Givens Sudoku drives by the fact that unlike other Sudoku types here we have to only enter numbers from 1 to 7 instead of 1 to 9. The remaining two digits are twin which is marked with blackened cells. These twins can touch each other only on corners.

Twin Givens Sudoku variation was part of Sudoku Mahabharat 2015-16 Twisted Classics Sudoku round at Logic Masters India website. Again this Sudoku is an easier Sudoku variation and has helped us to keep this test on the easier side.

This Twin Givens Sudoku, I am posting in Fun With Sudoku Series as 155th Sudoku in this series. Can you solve this Sudoku Puzzle?

Rules of Twin Givens Sudoku

Place digits from 1-7 in each row, column, and 3x3 outlined box. Two cells will remain empty as these are twins and of the same value. No two twins can touch each other in orthogonal directions.
