Xiumin making it known that he is only staring at you.
You turned to your friend and said "maybe he's staring at the person behind me". Your friend looks at you with disbelief and says "he's making it pretty damn obvious y/n" (your name). You, still being uncertain you turn around to look at who he may be staring at, you brought back your attention towards xiumin. Him picking up on what your thinking he does the hand sign from above, proving it's you that he is staring at no one else.
