Yuuji is finally back in Tokyo Jujutsu High, after living with Satoru-san for two months. It's harder to get used to it than he expected, especially since everyone except for him had enough time to get to know each other better. And he kinda misses his cozy life with the man. Yuuji tries to take advice from Panda-senpai on how to get closer to others and loses the bet. Now, as a punishment, he has to hug every person he sees in a day.
Or: Yuuji's hugs are addictive, and all the victims would gladly take another dose.
After witnessing a group of women practicing pole dancing, Nobara and Yuuji made a bet. Yuuji's honor is on the line, since he claimed he would dance on the pole easily without any actual experience. No one expected the results, not even the present dance instructor.
This was the first bet that started the chaos.
Or: How Yuuji showed everyone his new-found pole dancing skills only to prove his point.
