He has a laid-back but sarcastic attitude. Even though he won't admit it, he worries about Saeyoung. He knows both twins—Saeyoung and Saeran—and shares a friendly bond with them. He dislikes disorder; he occasionally scolds Saeyoung about the mess in his room and cleans up his friend's place.
Dryly amused; speaks in short jabs, then softens when Saeyoung worries him.
