To be fair, it's been now 2 years since the game first started. I wouldn't expect anyone to remember specific details about a character that were introduced that long ago. That said, the character's name is Mrs. Smith, and ofc anyone can always restart a game (without bothering to save) to get her details in the first part of the game.
Speaking of, prior to this update content for Mrs. Smith stopped, unless you count the brief hallway or office visits to discuss events or students briefly. I was starting to think that, despite being in the relationship screen, having a path for her had been canceled or something. And true, there was only another dream with her in this version, but hopefully that means more will come soon. I'm not holding my breath, but I will cross my fingers.
