SEVENTEEN's Seungkwan and TOMORROW X TOGETHER (TXT)'s Soobin, known as representative "K-POP experts" and close seniors and juniors, have become a hot topic by revealing their unique friendship where they rarely contact each other.

On the 5th, the web entertainment show "Seungkwan's Bibbidi Bobbidi Boo" on the YouTube channel "117" featured Soobin as a guest, showcasing his candid chemistry with Seungkwan. During the broadcast, Seungkwan addressed their unique communication style, asking Soobin, "We're famous for not being in touch easily; have you ever felt bad about that?"

Soobin responded by confirming their "cool" relationship, saying, "We only contact each other when there's a specific reason. Honestly, when there's no business, neither of us reaches out, which is very comfortable". Seungkwan added that while many people get upset when he doesn't reply, he feels at ease because Soobin isn't like that.

However, there was one exception: when Seungkwan is drunk. Soobin exposed Seungkwan's drinking habit, saying, "When he's drunk, he calls me at 5 or 6 AM and confesses, 'Soobin, I love you'". Seungkwan replied, "The person you look for when you're drunk is the one you truly miss, isn't it?" and expressed his special affection by adding, "I don't do that to any other younger friends but you".

Meanwhile, the two also displayed their extensive knowledge of second-generation girl groups like KARA and Wonder Girls, fully living up to their titles as "K-POP Associate Professor" and "K-POP expert" while providing great laughter.
