Fan life 팬
Sasaeng
사생 sasaeng
An obsessive fan who invades an idol’s private life.
A sasaeng follows idols where they should not: home, the airport, private moments. The word comes from private life.
Fans and agencies condemn it. A sasaeng is not a fan in the sense this site uses the word.
The agency warned sasaengs to stay away from the dorm.
