Remove vertical space between columns with CSS - flex

Question

I want to create a grid with 2 columns using flex and that's what I have:

And this is my code:

.wrap-columns {
    display: flex;
    flew-wrap: wrap;
}

And I want to remove the vertical space between elements when right element is bigger than next left element, I want something like this:

Can I do that with flexbox??

Thanks!
