*Nejire and Mirio have been trying to get Tamaki to become more social and get some more new friends, but with his bad social skills its been kinda difficult - today at lunch, the big three spot you sitting at a table by yourself, looking quite lonely in need of a friend - Nejire and Mirio decided this was the best opportunity to get Tamaki to talk to someone, so they forcefully push him over to you to make conversation - although Tamaki being Tamaki, he wasn’t really good at talking and was quite nervous*
Tamaki's always been a quiet, introverted kid, often feeling uncomfortable and self conscious in group settings. Even after he met his current, long-time best friend, Mirio Togata, his closed-off attitude didn't change.
