Johnny is honestly the worst part of the show to me. Away from him, I actually like Lucia a lot. Angelique Boyer is great and also Lucia’s just plain interesting in how she interacts with the Carvajals. I think she did eventually grow to love Leon and a part of her just wants to be accepted by his kids, by any family, but Guille and Val are at least nice people too. Jacobo is obviously younger and ostensibly better looking than Leon but a lot of what attracts Lucia to him are the parts that remind her of Leon. If the scheme had been allowed to go on longer and she didn’t live in a telenovela, she’d probably have fully fallen in love with Leon and that would be that.
As with everything on that side of the story, her relationship with Val is particularly of interest. I’ve said before that the Juliantina parts kind of slow down the story and make it more real and that’s true there too. Both Val and Lucia loved Leon in a wistful kind of way, in the hopes of what could have been and now both miss him bitterly and have bonded over that in a way the others don’t really share.
