Well, acting and making decisions on emotion can work out in real life, the thing is, you need Talent. If you aren't skilled enough, acting on your emotions rather than judgement leads you to failure. The MC is actually very talented, raised in an emotional environment along with being raised by somewhat emotional people, meaning his whole environment essentially encourages emotion, and he's also Still a kid, no matter who's on the inside. He ought to think with his heart first, it only makes sense.
If he does learn to think with his head more, it'll be later, but some people, even in real life, are emotionally driven, and some even regularly succeed. It's a flaw, but it's not a negative flaw, it's neutral.
So I don't think I agree that the flaw lingers longer than it should, I think it fits fine for the character as a person right now.
I get what you’re saying, and I agree that emotionally driven people can succeed—both in fiction and real life. I’m not arguing that his behavior is unrealistic or unjustified. It absolutely fits his background, age, and environment.
My issue is more on the narrative side than the character logic itself. When the same emotional decision-making pattern keeps repeating with minimal variation or consequence, it starts to feel less like intentional character exploration and more like stalled progression. A flaw can be neutral and still become narratively repetitive if it isn’t challenged, redirected, or contrasted often enough.
So for me, it’s not that he “shouldn’t” think with his heart—it’s that I would’ve liked to see more gradual shifts, hesitation, or learning moments layered in sooner, even if he ultimately stays emotionally driven. That contrast is what would’ve made the growth feel stronger.
That said, I get why it works for you at this point in the story. We’re just weighing realism versus pacing differently.
I'm a writer at my core so I understand you, I just don't think it bothers me since it's just one of many things I read so I just choose to enjoy what I have
Overall I enjoy the MC and the concept, but one flaw stays consistent from beginning to later chapters: he keeps making decisions based on emotion rather than judgment. Especially when someone vulnerable is involved, he tends to act on “I can do it” even when adults or allies already prepared solutions. It usually works out, so the story never really challenges this behavior or lets him learn from it. If the author had shown consequences, hesitation, or more trust in others, the character growth would’ve felt stronger and less repetitive. The intention is good, but the execution makes the flaw linger longer than it should.
