I want to create a Relationship Point System similar to Telltale's TWD in Ren'py

Hello everyone.

I'm currently planning on starting a project using the Ren'Py engine and I was thinking for ways to make it feel a bit more active/interesting than your average VN so I decided to look at one of my favorite game series which is Telltale's TWD.

I thought including it's "point based relationship" mechanic would be cool. Depending on how you choose to interact/talk with the characters, their dialogue towards the mc would change. Be nice to a character, they treat you with care, be somewhere in the middle which leaves it up to the characters' personalities on how they treat you, be an asshole, they return it to the sender. You get the point.

I want to make something akin to this and I was wondering if someone who doesn't really know any coding might be able to accomplish this? If so what should I know??
