Is dai dead?
There's a lot left up to the reader here. The mangaka didn't give us any confirmations and I think that was because there's no real ending that would be ideal for it. It could go any away. Dai dead or dying, Dai alive and Jaehee finding him.
Personally, I am convinced Dai is still alive. Whether he'll stay that way for long or not I have my doubts about. If that guy in the cabin was Dai, he was not in a healthy state. The whole thing screams cancer to me. But I think that's why the meeting was important too. To evaluate if Jaehee could now live without Dai. He clearly couldn't. So I think Dai decided to take him back. I think they reunited. I think they were happy together. I think Dai was sick and likely ended up dying and I think Jaehee followed him down.
It's just as valid as what I think.
I hate unhappy endings. I'm a more fluffy, happy until the world collapses kind of person.
So I think the mangaka did the best thing here. Whatever ending you need to finish this off, to resolve this for you, you can have it. It really is up to you.
Happy and living a long life is a nice ending. Considering how much they went through, it would only be fair really.
