YeoJin (single album)

YeoJin is the fourth single album by South Korean singer YeoJin, a member of the girl group LOONA. It was released on January 16, 2017, by Blockberry Creative. The single album is part of LOONA's pre-debut project, which introduced each member individually before the group's official debut.

The single album consists of two tracks: the solo song "Kiss Later" and a duet with fellow LOONA member HaSeul titled "My Sunday." "Kiss Later" is a bright and energetic track with a playful concept suitable for YeoJin's then-youthful age. The music video for "Kiss Later" depicts a whimsical storyline and features a guest appearance by LOONA member HyunJin. "My Sunday" contrasts "Kiss Later" with a more mellow and harmonious sound, showcasing a different side of YeoJin's vocal capabilities.

The release of YeoJin contributed to the overarching LOONAverse storyline, adding to the lore and connection between members that the pre-debut project aimed to establish. The single album received attention for its distinct sound and visual presentation, furthering the momentum of LOONA's pre-debut activities.
