@qazpalm: I get what you mean! Sometimes I have to remind myself that Alejandro isn't really "a baby boi," either
though I still call him that. The thing is, the narrative itself isn't suggesting that the romance between him and Ibelina will start when he's 13. Yes, the romance has started with his crush, but the actual
romancing has not. Right now the narrative is explaining why Alejandro has a crush on Ibelina, which will play an important role later on in the story. His crush is supposed to be cute and endear us to him. Make us laugh, even, because poor Ibelina has no idea what she's doing to this cute "baby boi." The meat of their actual and mutual romance will begin after a time-skip. That's when we start the romancing.
I doubt with her current mindset Ibelina will want to be with him romantically, anyways—even she sees him as kid. 😂 RIP, older Alejandro. He has his work cut out for him in escaping the baby brother-zone and convincing Ibelina no, he will NOT fall in love with Elenora.
