It was a statement handed to SHINee's Key by BTOB's Lee Chang-sub on MBC's 'I Live Alone'. Key had recently embraced the number one trophy on MBC's 'Show! Music Core' as a member of SHINee. Despite being 15 years into his debut, Lee Chang-sub sincerely congratulated Key on the robust activities of SHINee.

Just as Lee Chang-sub said, Key demonstrates an enduring prominence in K-pop, energetically pursuing both SHINee group activities and solo endeavors. Key has been continuously challenging himself musically, flaunting his diverse charm as a group and as a solo artist, given his robust domestic and global fandom.

Last month on the 26th, SHINee, including Key, released their 8th full album 'Hard' and promoted it actively. The album's orthodox hip-hop dance song 'Hard' contains SHINee's will to not give up on challenges and to keep moving forward with their beliefs. Despite their 15th anniversary, the members' strong passion to continue their musical challenges is distinctly felt.

This year, Key also spread a fresh charm different from his previous image through his solo album. In February, he unveiled a retro sound based on 80s new wave and synth pop through his 2nd full album repackage 'Killer'. He exhibited a kitschy feel with vintage items and even exuded a strong charisma by getting on a bike in the music video.

Key, who constantly takes on new challenges through group and solo music activities, is also an indispensable talent in the entertainment industry. He's adding fun for viewers with his witty remarks through MBC's 'I Live Alone' and tvN's 'Amazing Saturday'. Especially on 'Amazing Saturday', he surprises the panels every time by perfectly mastering the choreographies of recent popular songs.

Key, who has been active for 15 years, has conquered the entertainment industry with trendy music and witty remarks. Regarding Key, an official from SM Entertainment recently introduced to News1, "In a word, Key is a very smart guy. He has a lot of ideas, and he always clearly knows his role in all activities, including within SHINee, solo activities, variety shows, and advertisements. He constantly upgrades himself by deeply pondering what he should do."

The official added, "This harmony of characteristics has probably made Key the beloved figure he is now by not only music fans but also the public. He is a figure where natural sense, smartness, and ceaseless effort harmonize well," emphasizing his sincerity and effort. They also praised, "Because he clearly perceives the situation and acts sensibly, it's comfortable for the staff to work together, and it creates synergy."
