On the November 3 broadcast of MBC's 'I Live Alone', SHINee's Key took on hiking on his search to find healthy, new hobbies.

On this day, he went along with his friend and hoobae, NCT Dream's Renjun, a self-professed avid hiker. The two artists visited Daedunsan (Daedun Mountain) in Chungcheongnam-do, known for its high peak and a thrilling sky bridge on the way. 

While the young and energetic hoobae, Renjun, demonstrated his agility just like a flying squirrel, Key was drenched in sweat and breathing heavy after the first few paths. No matter how many stairs they climbed, the trail seemed never-ending, but finally, the duo reached the wide open sky bridge and snapped some Instagram-worthy photos.

After reaching the top, Key caused laughter with the elaborate(?) lunch he packed for himself and Renjun, which included slices of toast, tuna, cucumbers, and a whole bar of cream cheese. Renjun was more focused on drawing on his tablet than eating, until Key fed him a spoonful of tuna and activated his tastebuds. 

Finally, the two artists wound down with a healthy jeongol (hot-pot style stew) meal after climbing down from the mountain.
