Yes he does!!! And it is glorious!!!
What chapter does it happens
In the novel yes the manhwa has yet to adapt it
There's a novel too? Is it completed? Where can I read it? Or can I buy it?
The novel is officially on webnovel.com and manta.
Here is a link to where I read it https://novellive.com/book/under-the-oak-tree
quick disclaimer the novel is nsfw and has all the sex scenes the manhwa "fades to black" over
It is completed but there are mixed reviews
You can go to amazon to get the pdfs the first and second volume of the novel but the third is still on preorder
The official english translations chapter by chapter are here https://m.webnovel.com/subject/345219072654445 but also on goodreads https://www.goodreads.com/series/339570-under-the-oak-tree-novel
For more info you can ask at the subreddit r/undertheoaktreebook
