Paritucularly, ILLIT and TVXQ caught the most flack from netizens for their raw live vocals.

• “TVXQ have been around for how many years now, lol — they’re still the same.”
• “TVXQ is flustered;;”
• “It’s a live broadcast, it’s just a different stage lol — it even says ‘live broadcast’ in the top right. Don’t lie just because you can’t read Japanese.”
• “Oh, this group…”
• “With ILLIT, it varies a lot depending on how they use the member with lifeless eyes and how they handle Moka.”
• “Wow, ILLIT was really bad… the company is the problem for even thinking of debuting them.”
