I don’t read them anywhere special or specific, haha. Quite unremarkably, I pretty much just google manga, and read it on whatever site happens to come up (though once in a while, I’ll download the scanlated pages straight from the translators.)
I do tag all my posts but anyway, the manga you’re looking for is called Sakamichi no Apollon/Kids on the Slope and you can read it here!
Ok if you hover over the pictures on the blog, in the bottom-right corner you should see a number [signifying the number of notes the post has]??? Click it and it should be smooth sailing from there ヽ(*・ω・)ﾉ
