A Fan’s Unexpected Interaction With Popular 4th Gen Male Idol On Train Goes Viral

An unexpected encounter with ATEEZ’s Seonghwa on a train is gaining attention after a fan revealed the incredibly thoughtful way he responded when they asked for an autograph.

According to a post shared online, the original poster’s friend happened to randomly run into Seonghwa while traveling by train. The encounter itself was already an incredible coincidence, but there was one small problem: the fan apparently had nothing suitable for Seonghwa to sign.

Rather than simply apologizing and moving on, Seonghwa came up with his own solution.

“No, but I wanted to get an autograph, but I had no where for him to sign. So he said he had some postcards in his luggage and that he would sign them for me. He took postcards from his luggage and signed them with eyeliner.”

Even more adorably, Seonghwa reportedly didn’t just grab a random postcard. According to the account, he pulled out several different postcards and showed them to the fan, telling them to choose whichever one they wanted before signing it.

오늘 트친이 기차에서 성화님 자만추 했는데…
싸인 받을 곳이 없다 하니까 자기 캐리어에서 엽서들 꺼내서 싸인해줬다고 함! 엽서도 여러개 보여주면서 원하는 거에다가 싸인해주겠다고 고르라고 했대요 ㅋㅋㅋㅋㅋㅋ

A complimentary tale about ATEEZ’s Seonghwa. Today, my moot ran into him on the train. They didn’thave anywhere for him to sign on, so he took postcards out from his luggage and autographed them! He even showed them a couple of different postcards and told them to choose which he’d sign on LOL. I’m posting it in their place because it’s been a long time after he got off at the station.
