For those who haven't read my other fic Punishment, you have to read it to know what's going on so you won't be lost. 

Here's the same information from Punishment to keep in mind as you read:

Alphas, Betas, and Omegas take suppressants but in small dosages because Wolf culture is wanted by the fans, so only the deepest of instincts are suppressed. This helps idols because they don't grow sick from heavy suppressant use.

• Alphas don't go into a rage when smelling Omegas because of suppressants. 
• Omegas go into heat but have birth control.
• They all take pills to dull their scents, which can quickly go through the bloodstream if needed. 

Jin – Alpha
Yoongi – Beta
Hoseok – Beta
Namjoon – Alpha
Jimin – Omega
Taehyung – Omega
Jungkook – Omega

Jin is the head Alpha even though Namjoon is the leader.
