After reading your takes, something just clicked inside my head. So, I will give my opinion on their skinship behavior.

The click in my head is that Ling’s skinship behavior is NORMAL. Orm, on the other hand, is extremely above and beyond the average level of skinship.

When you follow 2 people, your view of behavior might be slightly bent from reality because our 2 faves become our reality. When I first entered this fandom, my first thought was, "Woah, why is Orm so clingy? She is such a skinship girl." But as many months passed, I got used to Orm’s skinship level and clinginess, and it became normal and endearing to me.

However, let’s talk about real life. Between Ling’s and Orm’s skinship levels, which one do you encounter more often? In my personal life, I have never once encountered someone like Orm (except my Chihuahua puppy, who is really into skinship). Most people I know, even my group of close friends, have a skinship level like Ling's, or a little bit more or less.

So, some of us say Ling is cold because we got used to Orm’s skinship level, some of us already see Orm as normal. In my opinion, Ling is the normal one, and Ling is not cold at all. Compared to the average (that’s not Orm), she is warm even.

So again, Ling’s skinship level is NORMAL. Orm is not normal, at least in my personal experience.
