The issue with Wei Wuxian's body

So, I started reading MDZS and I'm at the 2nd chapter of book 2. And at this point of the story, there is a doubt that is assaulting me, specially regarding the future relationship of Wei Wuxian and Lan Wangji... so what happens with WW body?

The story doesn't delve much into in (up to where i'm reading at least), but of course the body of current WW must be totally different to what he was before dying. And if LW liked him since they were younger, wouldn't it be shocking suddenly having this different body in front of you?

While I'm not fishing for spoilers, it's something that is bothering me a bit 🤣specially coming from SVSSS where the body replacement thing happens too and is not really addressed.

Does WW turn, in time, more into how he was in the past, or it becomes just a secondary matter where LW doesn't care because he sees WW for what he is inside?
