Bilhete de Vingança (2017)

Both have similar plots just in DN, its a guy who gets hold the death note and uses it to punish criminals. As you can see its much darker than SR. In sweet revenge, main girl receives a not that gets revenge on the person's name written in it.

Both have a main girl and are in high school and have a fantasy side.
Th drama treat many students cases too but Revenge Note is way more light and cute than Nightmare Teacher

Both stories:
* are short and sweet
* have fantasy elements to aid the female lead
* have a pretty male lead and a plain female lead
* have a love triangle

The settings are different, one is in the workplace, the other is in high school.
But the plots are all about the female lead using a mysterious APP to help her colleagues/classmates and herself, falling in love with the male lead in the process.
These dramas have very little 'drama', they are really light, short and funny to watch~
