wait, who was saying the 'he's really easy' line? which one of them?

blonde guy but it could be both (〜￣△￣)〜

It was yura-san (blonde)

it could be that the blonde said the first part and the black haired guy said the second part (to show that they were both manipulating each other)

I thought it was an artistic way of showing how they are playing each other without even knowing.
