The script for Komi's play is really the reflection of what Komi and Tadano have been gone through since their first year in high school. That's why, both of them able to stay in character in the play. Whenever Komi is in trouble, it's always been Tadano that help her. From how she's always awfully shaking whenever she met with people until how she's slowly able to calmly communicate with others with the help of her notebook.
Tadano is a special existence for Komi since he is her first friend and first love~~
