It takes more than just good looks to become a K-pop idol. One of the characteristics that are required to become an idol beloved by many is personality.

Of course, the fundamentals of being a top-tier idol are talent in singing and dancing, but a truly unique personality can be what draws fans closer to the idol.

Recently, TXT member Taehyun's interaction with a fan on Weverse is garnering attention as many are fascinated with the amount of information that the idol provided to the fan.

One fan wrote on Weverse, "Taehyun Oppa, I really have something I'm curious about. Do mosquitos not sleep?"

In response, Taehyun wrote, "I remember looking this up when I was raising a beetle when I was in elementary school..." He continued to write, "Surprisingly, a lot of scholars researched this because of their curiosity of if insects sleep as well. First, insects do not have eyelids so even if they are sleeping, we can't see if they're really sleeping or just resting with our human eyes. There were those who said that insects don't have brains that are developed enough to need sleep but then later they concluded there are insects that do need sleep. Also, I think the answer to this question would change depending on the definition of sleep!"

One netizen shared this interaction in a popular online community and wrote, "Why does he know that? lol. I really want to debate with TXT's Taehyun one day, I feel like I would lose real bad."

Other netizens and fans joined the online community and commented, "I use Taehyun's Weverse like Wikipedia," "His personality is really unique," "I feel like if Taehyun would have been a professor who knows random facts if he didn't become an idol, lol," "I think it's funnier that a fan asked that question, lol," "He's so thoughtful giving the answer, lol," "I think he really likes knowing these random pieces of information, lol," and "He sounds so smart actually."
