In SBS Running Man' broadcasted on the 8th, Parallel theory is revealed between Yoo Jae-Suk and Yoo Seung-ho. The recent recording was the signature relay Grim mission of Running Man'. Previously, the members showed incredible unity with all kinds of tricks when they made a Grim mission every time they made a Grim mission, but this time, the upgraded contest was held by combining the character quiz and Grim. Yoo Jae-Suk and Yoo Seung-ho came out as the first runners of the relay Grim. Yoo Jae-Suk showed a unique style every time a Grim-related mission was given, which made the scene embarrassing. Again, I appealed to my confidence that "I only draw points!" And "You have to understand my style." Yoo Seung-ho was also confident with a smile, and Yoo Su-bin cheered, saying, "Yoo Seung-ho is from the gold medal of the art competition." After the full mission began, various stars were presented, and the two burned their art souls. Yoo Jae-Suk expressed all the characters in short and bold points, while Yoo Seung-ho shocked everyone by creating a "half-person" figure. When the unexpected Grim appeared, the members laughed at the Parallel theory about the Grim ability of the Tuyu Brothers, saying, "I think they are going through something" and "I have to look at it as a magic child."
