Komi Can't Communicate Vol. 3 (manga)

Summer is about to begin, and Komi would love to be able to spend the long, hot vacation days hanging out with her new friends. But even though she's made great strides in her personal quest, she still has problems communicating. For instance, making phone calls is so anxiety provoking that it keeps her up at night. Thankfully, Tadano always seems to know how to help her calm down!
