Taeyeon is obsessed with PUBG apparently, and the last two videos on her YouTube channel revolve around it.
In the first she mimics dance emotes in public much to her own embarrassment, and in the second she gets a gifts from PUBG only to use them to also mimic dance emotes.
Taeyeon comes off like an incredible nerd in these, which is great, and now I’m pissed that nobody tipped me off that she had a YouTube channel earlier.
