To be honest, I wouldn't assume that some 13 yr old kid who looks like he's 8 is in love with her either. From her perspective, he's still a child and destined to fall for another chick. I would think he's being possessive and obsessed since she's the only one who shows him kindness. So don't blame Ibelina for being clueless about his feelings.
Alenjandro is pitiful and cute, but can't see him that way. I actually don't mind if this story is all about platonic love, but maybe it won't sell that much?
