This trope is so overused in BL.. its crazy. Also, its the weird implication the children that are not genetically related to each other and to their parents will NEVER be family. Why is that an implication? It's so harmful for actualy people that are adopted. An adopted child is a child. It's not one of my own and one adopted, it's 2 of my own regardless. Siblings who grow up together are also brothers especially if they were raised like brothers, acknowledged each other as brothers for majority of their life. That doesn't just become romantic one day. It's unnatural.
I'm not mad with the brother thing; I'm just upset it wasn't written well. Like why? Stop adding every trope just because you can without any logic! There are some stories where it is done well and even makes sense. In those scenarios, they never considered each other as siblings, may have even grew up separately, or had been in love since young so it isnt a weird brother to lover change. This though? Its ick.
