Theres a manga where they aren't fated pairs but the alpha bite him he belong to the one who bite him. The fated pair guy (alpha) just think about regretting not biting him. Then the alpha met his own fated omega but he stay faithful to the omega he bite.
May I know the title?

Guy got bit by an alpha who is not his fated mate but childhood friend.
Awww that was a good read.
I’m wondering even if an omega/alpha finds his fated pair, can they mate with someone else. Like let’s say the omega goes into heat & a nearby alpha bites them & they mate. Like I’ve read omegaverse where a alpha rapes & bites the omega b/c they were aroused by the omegas heat & they become partners. I guess it’s varies by author b/c in “Love is an illusion” they didn’t realize they were fated pairs until the omegas body rejected another alpha.
