Han So-yeon suffers from aphasisa and nobody knows, except for Holo. She has been asked by the director of the company that she works for to help him welcome people at an event. her job would be to have an overview of who`s who and whisper it in the director`s ear. Holo decides to help out after she is failing on her own.
The technology is still a part of the character Holo`s function, but we need to have the tech, so I give Holo the more general action which is in this case assisting, and the tech get more the specific functions, even though they are the one and the same.
