i think lim prefers to bottom when in heat. from what weve read, lim still has a dominant side and likes to top, and hae-il said that he bottoms and tops. from that i gather that theyre both versatile but have a preference for when they are in heat or rut.
i dislike having set bottom and top roles in a lot of manga only because it feels like the author is using the bottom as a female proxy, imposing heteronornative masculine-feminine norms in a male homosexual relationship.
however, in this case these characters preferences just depend on their mood and biological cycles. lims still a cool man. hae-ils still a cool man. if lim is an omega that likes bottoming with his alpha partner because he enjoys being entered most of the time, so be it.
*heteronormative masculine-feminine stereotypes, not norms
I was having fun with him being an omega that tops
