Kyou, Eki de Mita Kawaii Onnanoko - Vol. 1 Ch. 9

[Naruto031]

I completely forgot what this manga was all about 😅

I assume he’s just saying “nii-san” or so but it sticks out when translated bc irl siblings don’t always call each other bro/sis rather than their names or it’s a nickname among friends/just a casual way of calling someone like you would say “dude” they also say Mr Kameyama rather than Kameyama San too

It's a cultural thing. Most Asian country don't refer to older sibling with name,it's more natural for us to just say big bro big sis or such. Translating it other way where he called him by name I'd argue is the weirder choice
