Under the Oak Tree 상수리나무 아래 is a very popular Korean webnovel, well, apparently it is a very FAMOUS novel which I just found out, LOL… I have never heard of it until today after I came across the OST, and then checking out the novel! It is an on-going serialized novel beginning in 2017 written by Sooji Kim 김수지 and it has been adapted into webtoon since August 31, 2020. The English version of the webtoon is available since the beginning of this year.
