SEVENTEEN JOSHUA is the chef at BYOB today! JOSHUA is ready to get all the random ingredients with his challenge skills from GOING SEVENTEEN. Guess what ingredient is hiding behind box number SEVENTEEN! Watch for the chemistry between Joon & Brian and Joshua! No wonder he's a SEVENTEEN member. Joshua calls a SEVENTEEN member during the show but guess who is in the shower… p.s. JOSHUA is so happy to be here alone (so happy he forgot to mention SEVENTEEN's 10th anniversary)
