Birth Name: Jeon Heejin Birth Date: October 19, 2000 Color: Bright pink Animal: Rabbit Reveal Date: September 1, 2016 Pre-Debut Date: October 5, 2016 No. of Pre-Debut Songs: 13 Sub-Unit: LOOПΔ 1/3 As I mentioned in the opening post, the LOOПΔ pre-debut project officially kicked off on September 1, 2016 with the release of a then-15-year-old HeeJin's first batch of teaser photos. Another photo teaser and her first video teaser were both revealed on the 25th, followed by the reveal of her title track's name and its MV teaser on the 28th.

On October 8th, HeeJin had her first fan event to celebrate the successful release of her single. LOOПΔ TV #1 launched on October 13th, with its first arc covering the shooting of HeeJin's photobook and music video. By October 16th, "ViViD" had already hit 100k views on YouTube, and HeeJin released a short clip thanking fans for their support. The 100% Real Live version of "ViViD" was uploaded on October 19th as a gift to fans on HeeJin's 16th birthday. A Choreography Practice ver. of "ViViD" was released on December 28th as a thank you gift for the original MV reaching 300k views. HeeJin is arguably LOOПΔ's strongest all-arounder in terms of nailing any concept given to her. She's a born star - naturally charismatic, skilled in both vocals and rap, and a fantastic dancer.— Birth Name: Kim Hyunjin Birth Date: November 15, 2000 Color: Yellow Animal: Cat Reveal Date: October 28, 2016 Pre-Debut Date: November 17, 2016 No. of Pre-Debut Songs: 11 Sub-Unit: LOOПΔ 1/3 On October 24th, the first Who's Next Girl? teaser was released, followed on the 28th by HyunJin's reveal through her first teaser photo.

On January 14th, the "I'll Be There" Choreography Practice ver. was released as a gift for the original MV hitting a views goal of 200k. What HyunJin lacks in vocal technique, she more than makes up for with her hilarious personality, barking skills, earring-modeling, and powerful dancing. Her solo may be the blandest pre-debut title track, but HyunJin herself is anything but.— Birth Name: Jo Haseul Birth Date: August 18, 1997 Color: Green Animal: White bird Reveal Date: December 8, 2016 Pre-Debut Date: December 15, 2016 No. of Pre-Debut Songs: 11 Sub-Unit: LOOПΔ 1/3 HaSeul's Who's Next Girl? teaser was released on December 1st, followed by her full reveal on December 8th.

On December 31st, HaSeul had her first fan event alongside HeeJin and HyunJin. LOOПΔ 1/3's leader is one of the sweetest girls, and is like a mother to the whole group, especially YeoJin. A trained opera singer, but that doesn't mean she'll be getting lines in OT12 releases anytime soon. She also has terrible luck with the weather.— Birth Name: Im Yeojin Birth Date: November 11, 2002 Color: Orange Animal: Frog Reveal Date: January 4, 2017 Pre-Debut Date: January 16, 2017 No. of Pre-Debut Songs: 3 Sub-Unit: П/Δ On December 30th, YeoJin's Who's Next Girl? teaser was released, with the full reveal of the then-14-year-old following on January 4th, 2017.

LOOПΔ's deep-voiced brash and bratty maknae (although she's mellowed out a bit now) is the odd man out in the group. Although she was meant to be the / in LOOПΔ 1/3 at one point, she is the only member without a sub-unit.— Birth Name: Wong Kahei Birth Date: December 9, 1996 Color: Light pink Animal: Deer Reveal Date: February 13, 2017 Pre-Debut Date: March 13, 2017 No. of Pre-Debut Songs: 10 Sub-Unit: LOOПΔ 1/3 On February 1st, the first LOOПΔ 1/3 teaser was released to social media, with a video teaser following on February 6th, asking fans to vote for three of the then-revealed members who would then debut with an unrevealed member in a new sub-unit.
