The anime that broke your heart?

Domestic Girlfriend, because oddly enough I had a lot of the same teacher-student relationship experiences shown in the anime and manga. Watching and reading it felt so personal and actually really gave me a lot of closure on some issues from my past and really allowed me to look at them from an outsider's perspective. A pretty weird choice and response from my end, but honestly I hadn't cried as hard as I did in a very long time, reliving some moments in Domestic Girlfriend that were almost exact situations I had been in.
