Han Wangguk is a recurring character in How to Fight/Viral Hit.
He and his sister ran a NewTube channel called "OnePunchTV" under Seongjun's direction, with Wangguk handling the camera work. Their content strategy was pretty shady—he'd dig up dirt on popular influencers so his sister could call them out and rack up views. Things went south when Yeo Rumi fired back at his sister for her manipulative behavior and insecurity, which didn't sit well with the pink-haired girl.
Desperate to salvage things, Wangguk convinced his sister to falsely accuse Yeo Rumi of selling CP and engaging in compensated dating back in middle school. The accusation spiraled into a full witch hunt against the beauty influencer. Yoo Hobin eventually had enough and exposed "OnePunchTV's" corrupt practices to the public.
The fallout was brutal—Wangguk and Hobin got into a heated fight that Hobin won. After that, Wangguk bailed on NewTube entirely and picked up part-time work as an errand boy at a photo studio.
