hi! assuming you're from the us, looks like it's still on amazon? if you're not from the us, i also saw a shopee link when i searched up 而立·24. i know it's also on taobao if you'd like to use a forwarding agent!

there's no official english translation, but a bunch of translators got together and translated the book! the link to the google doc is in the tweet. i hope this helps :D
