Male: idols who are hardcore otaku/nerd like Heechul. He seems to know his shit. Our age is pretty close and sense of humor is kinda similar.
Female: I probably would just get too nervous in front of my biases. Maybe some more extrovert ones like Sana or Yerin could make me more comfortable. Maybe gamer/nerdy ones like Mina, Hayoung, or Sakura would be better, as sharing interests is always good in a friendship.
