So my ideas, the first one is Buck meets Aiden Shepard the male oc. Who is army reserves and in the LAPD, Aiden is also special forces apart of the special forces unit called Ghosts. They meet via Athena and her friends. Second idea Aiden is a hockey player for the Los Angeles Kings. He meets Buck at a charity event that the team held for the LAFD. Hen can point out to Buck that Aiden was flirting with him, they exchanged numbers and start talking and spending time together. And the third idea that Aiden and Buck are already married and Aiden runs for president
