In '300', artists team up with 300 of their fans and put on a large-scale, modern choir performances. However, if the artist and his/her team fails to fill the 300 fan attendees mark, each absent attendee marks a minus point. This week on Wheesung's team, 262 fans were present, taking off 38 points from Wheesung's team score. 

iKON on the other hand, became the first artist ever since the premiere of '300' to have all 300 fans present! After finding out that all 300 of their fans had come as promised, iKON couldn't hide their happiness. B.I. relayed, "I'm getting goosebumps. Thank you all so much for coming. We haven't even started our performance, but I'm already feeling electric. We sincerely thank you." 

[SPOILERS AHEAD] 

Along with their large team of 300 fans, iKON performed a remix of "Love Scenario" and "B-Day"! On the competing side, Wheesung performed "Insomnia" with his fans. Ultimately, Wheesung's team scored the most points and took home the win. But rather than focussing on the competition, iKON and Wheesung complimented each other on their stellar performances.
