Intro. We live in a world where there are several gender categories: Enigma, Alpha, Beta, Omega etc. The Alpha members are Bangchan, Changbin, Lee Know, Hyunjin. The Enigmas are: Lee Know and I.N. The omegas are: Han. The betas are: Seungmin, (Felix). The couples: Chanmin (Chan and Seungmin) and Jimin/minsung (Han jisung and Lee know) are a couple and the other members... it's up to you. Félix was a beta or was because he transforms a little bit into an Omega dominating the transformation above all and very slow painful and subtle at the beginning he didn't really pay attention he just had nausea sometimes dizziness suddenly in addition to these chronic pains but he still doesn't suspect what's happening to him he has hot flashes and so on and he starts to smell odors on the limbs which couldn't be defined but which was specific to everyone the others also noticed changes towards Félix...a smell that was born...
