Does anyone know where can i buy the physical copy of this?

Go to Japan and buy it at a manga store. Easy

You're not even helping, uncle (︶︿︶)＝凸

There are only 2 chapters of raws available, so it's not even available in a manga store in Japan yet.

Usually manga that have been published into tankoubon are sold in Amazon Japan, and some even can be shipped overseas.
