Just sharing my opinion. It may not be direct incest but the thought of it is disgusting. The fact that they grew up together as SIBLINGS, and that his mother picked mc up to raise as her child makes me really uncomfortable, it's like adopted siblings, while they're not related by blood, they're still step-siblings. And it's just gross to think about it y'know :/ so tired of having step-brothers as the love interest (for example Recording Hall, Beware of the Brothers etc.) because I couldn't give two fucks about whether they're blood-related or not, they see each other as siblings (when they're still young at least) and one is adopted.
