Minhyuk must have been feeling a bit lonely on MBC's 'I Live Alone' as, on the August 14 episode, he rang up his former 'Heirs' co-star, Kim Woo Bin!  Their affectionate conversation will have fans going "awwww."

Once connected, Minhyuk said, "Hyung, you picked up right away.  What were you doing?" and Kim Woo Bin cutely replied, "I thought you were going to call, so I was holding onto my phone." Smooooooth.

Minhyuk continued, "I heard you were good at basketball," and Kim Woo Bin might have the height for it, but he said, "Me?  I don't even know the rules," causing laughter. 

He then asked why Minhyuk brought this up and the idol replied, "I need to compete in the basketball competition for the 'Idol Star Athletics Championship,' so I called you to ask.  I'll see you soon," and Kim Woo Bin replied, "I'll call you. Make sure you eat."
