A drive for growth
Wood is the strongest force in their combined Saju, giving the group an incredible drive for growth and new beginnings. It provides a flexible, creative energy that allows them to branch out into different styles while staying rooted in their shared identity.
A steady foundation
Earth serves as the essential second element, providing the stability and structure needed to support all that expansion. It acts like the soil for the group's creative Wood energy, ensuring they stay grounded and work together with a reliable sense of teamwork.
The rare spark
Fire is the element they have the least of, representing the intense, outward-facing spark that keeps them in the spotlight. To balance this, members like Sejeong and Chungha carry their own personal warmth to the mix, ensuring the group never loses its passionate glow.
A versatile mix
Their Korean astrology reveals a diverse mix of seven different Day Masters, which creates a rich tapestry of individual strengths. This variety means that if you compare your own chart to theirs, you'll see how these unique personalities come together to form a well-rounded and versatile team.

Why I.O.I works

The bridge

Yoojung

Yoojung serves as a vital link between the members, as her chart shows the highest average chemistry in the group at 83. This natural compatibility allows her to navigate different social circles within the team, making her the perfect person to keep everyone feeling connected.

The stabilizer

Sohye

With two Earth elements in her chart, Sohye provides a grounding energy that helps keep the group's dynamics steady. This role as a stabilizer offers a reliable and patient presence that supports everyone else’s more active energies when things get busy.

The amplifier

Sejeong

Sejeong acts as the group's natural battery because she carries three Fire elements, the highest amount in the lineup. This allows her to amplify the team's presence on stage, radiating a bright and infectious energy that draws everyone's attention toward them.

The wildcard

Nayoung

Nayoung brings a distinct flavor to the group because her chart has the lowest similarity to the group average at 0.75. This makes her a valuable wildcard who can offer a different perspective or a unique sense of calm when the rest of the group is leaning in a single direction.
