What led to Miyeon's departure from Black Pink prior to their debut? Can you provide the specific reason behind her departure?

Prior to BLACKPINK's debut, Miyeon, who is now a member of (G)I-DLE, was part of the pre-debut lineup. However, she left the group before their official debut. The specific reason behind her departure has not been officially confirmed by either Miyeon or YG Entertainment, the agency managing BLACKPINK.

Some speculated reasons for Miyeon's departure include:

1. Dating Rumors: There were rumors suggesting that Miyeon was dating a contestant named Jinhyeong from the show "Mix and Match." This speculation led to her departure from BLACKPINK due to YG Entertainment's strict no-dating policy.

2. Addition of a New Member: Initially, (G)I-DLE planned to debut as a five-member group, but Cube Entertainment decided to include Miyeon as the main vocalist. This decision caused some initial opposition from other members.

3. Image Overlap: Fans speculated that Miyeon's departure may have been influenced by similarities in image with Jisoo, who is considered the group's unofficial visual. YG Entertainment may have wanted to avoid redundancy in image within the group.

Please keep in mind that these are speculative reasons, and the actual cause of Miyeon's departure from BLACKPINK remains officially unconfirmed.
