@Olotea pretty much this, is Alejandro not allowed to have a crush? Because he has a crush on Ibelina even though there is zero sexual interest from both it's automatically pedophile? Ya'll got the wild fucked imaginstions here.
The poor 13 year old was treated like shit by his family, his servants and others for his entire life and has had zero affection and lov3. He deserves to be loved and cared for. He isn't being groomed either ya'll need to look up what actual child grooming means. Ibelina has zero intentions to groom him for herself, author literally has been pointing it out multiple times in the story that Ibelina doesn't see young Alejandro that way, even before isekaing she's only shown to feel pity and care for Alejandro and wants him to be happy.
And when he grows up and fully develops and still loves her and both are within the same acceptable age range? So what? You want to damn his char development and happiness because it "feels ick" for you? Only person being icky is ya'll.
(None of this is towards you Olotea, it's to the people who are being dumb, not understanding and misinterpeting the story and character dynamics..)
