I always thought Zoe and Jim had quite a bit of chemistry.Side note - this has been mentioned before, but I feel like Jim would be a way better match for Zoe than Alfie. I haven't watched tonnes of his content but he seems way more mature and grounded.

And looking at how childish Jim is seems currently, it might even match
