Suggestions for East Asian/SEA locations for relaxing and lonliness?

Hi!

I've been solo traveling in Japan and dealing with some stuff, as 2024 has been a tough year. Japan is kind of my happy place, but I'm also starting to find it a bit expensive, so I'd like to move to somewhere quieter, cheaper, and more relaxing. It'd be great if I could find some places that's a bit easier to make friends, too. Essentially, I'd like to be somewhere beachy and just do nothing except maybe get some massages, zone out, possibly medidate, feel sad, and digitally nomad for a couple weeks while eating good cheap food.

I'm not particularly interested in the party scene (I wasn't very impressed with Bangkok or Chiang Mai for these reasons).

I've done a bit of research already, but I'd really love to hear some options. Here's some options:

Jeju Island

* Cheap(ish?)

* No car, so hard to travel

* Never been to Korea

* Beach

Bali

* Top option, but then I found out January is rainy season

* Maybe really touristy

* I like the idea of going on some meditation retreats for a few days

* Humid, which is a minus

Laikwang/Phuket

* Seem similiar?

* Probably not very expensive, massages yes

* Sun and snorkeling and etc sounds great

Hanoi

* Cheap, but dealing with hawkers, traffic, pollution etc. seem exhausing

* Cool European architecture

Any help would be really great. Thank you all.
