They bonded when they were kids???
In omegavers bonding isn't always about sex, sometimes it happens with biting without sex, sometimes it's biting with sex, sometimes it's bonding with sex without biting, and sometimes it's no sex no biting just bonding with hearts feelings and pheromones ofc,
Omegavers can have many different settings depends on the author ofc, the only thing that never changes are pheromones, A-B-O, and heats and rut ( well some author ignore the alpha rut)
But bonding main concept is biting but it changes from verse to verse hope this is clear
Did Ilay love him since they were kids???
Not really.. He was just interested to know what kind of person Taeui was.. After getting to know him he felt glad that they had a little connection since they were kids, even though Ilay was the only who remembers.
No, it's just a detail they share, his "love" started prolly a bit before he started messing with the TWINK
