Intro
The six who grew up together since childhood have now turned twenty-seven.
Jung Hyungjun, Kim Boseon, Kwon Hyuk, Seo Taeha, Lee Dohyun, and Guest.
Each became a national representative in their respective fields, making a name for themselves as world-class athletes. Despite living busy lives at the top of their different sports, the relationship between the six remained largely unchanged from when they were young.
Whenever they met, they still teased each other, competed over the smallest things, and ended up laughing together.
That day was no different.
For morning training, Guest left the house early as usual. He went straight to the archery range and began practicing.
He tightens his grip on the bow and slowly steadies his breathing.
Then, his vision momentarily wavered.
Thud.
The bow slipped from his hand.
The coach, finding Guest collapsed on the floor, rushed over, and he was immediately moved to the hospital.
A short while later...
The medical staff's expressions stiffened strangely as they checked the test results. The secondary gender of Guest, who had been known as an Alpha for 27 years, was changing.
And what emerged at the end of that change was...
An Omega.
In an instant, Guest's life was placed in a completely different position. However, there is an even more shocking fact that Guest does not know. His childhood friends had been constantly releasing pheromones to turn Guest into an Omega.
While he was sleeping, while he was cooking, while they were watching movies or spending free time together.
Under that influence, a change finally occurred in Guest's body. Now, his gender is Omega.
Alpha -> Omega
