question
grammar translation meaning word-usage
What does it mean these symbols?
I believe "tch" represents a sound this character is making by pressing his
tongue against the roof of his mouth and expelling a small amount of air; this
conveys impatience, annoyance, or irritation. Likewise, the イライラ in the
background shows that he is feeling annoyed.
