As far as I understand this they are playing a game in which they have to describe words shown on the paper non-verbally and Yae is showing the word "Temptation" so Itto refers to Sara (she is his temptation)
Can't really understand the arrow cuz I don't speak Korean but this is wholesome af

It's a Korean meme. They are playing a game of charades that just so happened to pick the word "seduction". Tagged it with the meme and found another example from three years ago.

Note that "yuhok" refers to the "act of temptation" and not just an "object/person of temptation".
