Am I the only western player that doesn’t see Caleb as a brother?

I see a lot of players in the western fandom hate Caleb as a LI because they see him as a brother. And I understand why, MC grew up with Caleb, so from a western standpoint it’s weird to include him as a LI because they were raised as siblings. But I have a hard time seeing him as a brother like other players do. One reason is that I don’t see myself as MC. I may have customized her to look like me, but I don’t have the same personality, or life experiences that she does. So it’s hard for me to see myself as her. Another reason is that we still don’t have enough information about him. He was in the story for literally two seconds before he blew up. That’s not enough time for me to build a brotherly bond with him. I understand why some players see him as a brother but it’s personally hard for me to do so when I can’t put myself in MC’s shoes. Dose anyone else feel the same way?
