There are people who forage for edible greens (namul) here in Korea, and people in other countries also go into the forest to gather wild fruits and plants (FYI, I’ve picked and eaten wild raspberries a few times myself and they were delicious). But you have to be careful since anything could be toxic, and it's super dangerous when a toxic fruit looks exactly like an edible wild fruit. Just like we have meoru (wild grapes) in Korea, North America and Europe also have wild grapes growing natively. Wild grapes are usually more tart than regular grapes, but they have a strong and unique flavor, so they have a surprising cult following. (Correction: While many wild grape varieties are tart, apparently sweet varieties exist rarely. Because they are wild, the taste isn't consistent even from the same vine, so they are mainly used for making wine or jam.) But there's something you need to be careful about...

This fruit looks super similar to a grape, but it's a berry called moonseed, which is highly toxic. (Couldn't find the Korean name no matter how hard I looked, sorry lol.)

Luckily, the leaf shape is slightly different, so you can tell them apart. It mostly grows natively in North America, but it looks like it's occasionally found in East Asia, so if you see a similar berry on the mountain, be careful. FWIW, I got interested in foraging after eating those wild raspberries and found this info while looking up warnings. If this post was interesting/cool, please toss me a recommendation!
