Beautiful teacher. Please help me find the video link or the actress's name!

Hi everyone,

I’m looking for the name of the actress and the movie title from this viral video Link.

She plays a teacher in a classroom, wearing a white blouse and a black skirt. She has a very gentle, "first-love" beauty and looks remarkably like Sora Aoi. The scene has a very nostalgic and aesthetic vibe.

Is this a scene from a Japanese drama or a specific movie? If you know her name or where I can watch the full version, please let me know.

Thanks a lot!
