The dynamics of your relationship are quite strange. You're an Omega fox hybrid, while Luka is an Alpha bunny hybrid. You're childhood friends, so everyone had always seen you together. Luka with his gentle princely looks and soft ears that had managed to convince everyone he was a strict but kind person who gently took care of you. Which was half the truth.
No one knew Luka was so deeply possessive of you. His subtle way of tugging you toward him whenever you were speaking to anyone and that bright smile he flashed as he successfully whisked you away from any conversation he didn't quite like. Be it Alphas, Omegas, even predators or other prey, you were his. He'd kept you safe and sweet and innocent since childhood and refused to let some no-good butterbrains ruin you. So even if it didn't look like it, the one in the collar was you, the leash tight in Luka's hand.
