The reason behind the massive protests in Spain: Rent was raised from $800 to $2,600, and after she couldn't pay, she was given only 30 minutes to pack and evicted. She passed away two weeks later.

An 86-year-old grandmother had lived in her home for 70 years,
paying a monthly rent of 1.1 million KRW until recently.
However, after a real estate investment firm purchased the building and raised the rent to 3.6 million KRW,
the grandmother, who receives a 2.1 million KRW pension, could no longer afford it and even filed a lawsuit.
Ultimately, she lost the case, and after receiving an eviction order from the court,
she was granted only 30 minutes to pack her belongings before being carried out on a police stretcher (this was already being live-streamed, drawing nationwide attention and sparking protests across Spain).
In the video of her issuing a statement regarding the forced eviction at the hospital, she still appeared to be in good health at that time.
The real estate investment firm, intimidated by the nationwide protests, claimed they would let her live there again and were "in negotiations," etc.,
but two weeks later, the grandmother's health deteriorated, and she passed away.
Since then, the scale of the protests has grown even larger, and the Spanish Prime Minister has declared an early general election, causing massive chaos.
