it's a superstition in Japan that when you're nervous you write the kanji for “person” on your palm with your finger three times, then “swallow” it. It's like a symbol for knocking down nervousness in short.
He traces the symbol 'ren' which is 人 meaning people. It's a thing in Japan to trace it on their hand and 'eat' it three times to calm nerves and ease anxiety.
Go google it, it's really interesting to read about lolol
he traces the kanji for man/people and its to calm his nerves (idk if its a japanese thing but ive seen other anime characters do it too)
I’ve been reading haikyuu for a while now and I’ve been wondering why asahi will trace something on his hand before a match. He traces a “y” like symbol and I am wondering what that means. Thank you
