MJ from ASTRO successfully held his first solo fan meeting 'The Hangout' at Seongsu Art Hall in Songdong-gu, Seoul on January 1st, marking his solo debut ten years after the group's initial debut. The fan meeting was held in two sessions at 2 PM and 6 PM, ahead of his solo comeback scheduled for the 19th, with a concept of casual chatting in front of a neighborhood supermarket creating a warm and enjoyable atmosphere. MJ opened the concert with the title track '계세요' and B-side '발렛파킹' from his digital single 'Happy Virus,' which challenged the trot genre, and showcased his diverse charms as an artist through various segments. He particularly impressed fans in the 'MJ's Roadside Chat' corner by empathetically listening to fan concerns and sharing personal experiences, while the 'Neighborhood Game' corner featuring capsule gacha missions with autographed poster giveaways heated up the venue. During the 'Playlist Talk' segment, MJ shared episodes behind his own songs including '12시 25분 (CLOCK)' and performed emotive live vocals, while also unveiling new tracks from his debut single album 'Right..?' scheduled for release on the 19th. MJ expressed gratitude to fans and promised to create more opportunities for future meetings, with his official solo comeback set for 6 PM on January 19th through various online music platforms.
