That is not what he meant. The night before he was thinking that, but when he went on their date he became jealous at the thought of Kanata loving anyone other than him and realized his true feelings. So he wasn't being selfish, he came to the realization that he has always loved him and will always love him as more than a brother.
You want him to always think of you as number one, but you want to also be allowed to date someone if you find someone you're more into later on?
You're kinda selfish bro
