Here's your magic square. If you don't know what is it, then I might tell you...

It's a square where the sum of numbers are 34 everywhere. (Diagonally only at the two biggest diagonal)

In this table, the numbers are from 1 to 16.

You have to fill this out in order to fulfil the sum of numbers, BUT you can only use a number once. (I recommend to save it in Paint, and solve it, it's the easiest way)

@Chlorede

Can you guess me in order to fulfil what you want?! This is what you know about me:

- I'm a two digit number and almost a round number.

- I can be divided by three

- If you add my sum of digits, you'll get 12

Who am I?
