Hurry Up and "Switch Sides" - S1.E9

Yuichi, who hasn’t left the starting point in the two days since the game began, suddenly announces his desire to switch to Group K. The Group K members, puzzled by Yuichi’s apparent intention to abandon his hiding teammate, ask their Captain to decide whether or not to let Yuichi in. Meanwhile, Tenji, who has stayed in hiding and trusted Yuichi all along, is finally reaching his physical breaking point.
