Omega Complex
Two childhood best friends. One manifest faster and become an dominant alpha in middle school while his friend stays a beta until later in life he becomes a recessive omega. The alpha HATEs omega due to the pheromones that they produce cling to very thing so his friend hides it when he becomes an omega. Fast forward 5 years and after not seeing one another they're both in college and secretly love one other. The omega finally can't keep it to himself anymore and tell the alpha...things get kinda weird for like a week and then they fall in love. Exchange rings (NOT married...yet) and love together with full time jobs.
