Apink.

Apink (에이핑크) is a five-member South Korean girl group managed by With Us Entertainment. Members include Chorong, Bomi, Eunji, Namjoo, and Hayoung. Their debut took place on April 19, 2011, under Plan A Entertainment (formerly A Cube Entertainment), which later became Play M Entertainment and then IST Entertainment, with their debut mini album Seven Springs of Apink. They debuted in Japan on October 22, 2014, with their debut single, “NoNoNo (Japanese ver.)”. After long years under IST Entertainment, the members chose not to renew the members' contracts—Chorong, Bomi, Namjoo, and Hayoung signed with With Us Entertainment in 2025, and Eunji left IST Entertainment the same year to join BILLIONS—while the act continues activities together.
