How to 🏐 #TXT #수빈 #SOOBIN

What happened

This is a TXT short centered on Soobin, framed by the title “How to” and a volleyball symbol, with English-language music as its audio.

Why Koreans care

The reaction hinges on “gap” appeal, a major K-pop fandom vocabulary for the thrill of an idol switching between contrasting images: commenters read Soobin first as a cute “rabbit” and then as unexpectedly sensual. Their repeated embarrassment about watching beside parents or on public transit reflects a familiar Korean online-fandom performance: exaggerating a mildly suggestive clip as if it were illicit viewing to dramatize how strongly it affected them.

What Korean viewers say

Majority: Commenters focus on the abrupt cute-to-sexy contrast: “From a cute bunny all the way to sexy, hahaha.” Majority: Several describe involuntary, embarrassing facial reactions in public or around family: “Ah, seriously, I accidentally put on a total middle-aged-creep grin on the subway,” and “My parents are right next to me, and I just made such a weird smile.” Fandom: Soobin is affectionately coded as a rabbit, while a moment near his neck is treated as the clip’s sensual trigger: “Bunny… when it brushed past his neck, I ended up squeezing my eyes shut.”

What you'd miss

“Gaejeossi smile,” translated here as “middle-aged-creep grin,” combines gae, an intensifier meaning roughly “damn” or “extremely,” with ajeossi, “middle-aged man.” The commenter is not making a demographic claim; she is mock-shaming herself for wearing an overly pleased, leering fan expression. Likewise, saying the video should be watched “in hiding” is playful overstatement, not a warning that the content is genuinely explicit.
