is there a novel for this?

I don't think so. Everything I've found so far points to it being an original webtoon

On ridibooks theres the novel and Webtoon but you’ll need adult verification to read the novel

What is the name of the novel ?

어프록시말 가이드 it’s a pretty short story from what I can see. You can go on baka updates manga for more info (๑•ㅂ•)و✧

There is a novel, complete with 159 chapters so pretty long! I googled the korean title 어프록시말 가이드 to find it

Is there an English translation??

Hiee can you please send me the link??
