Q5.1: Why is the MC monologue so confusing the first few chapters?

A: They have not decided what to call themselves at first but here is the definitive thing that they use.

I: The consciousness refer to itself as both bodies. The reason why I don't use We in this situation is because the consciousness considered both bodies are itself therefore doesn't use We because using it would considered itself a different entity from itself.

We: Refer to themselves outside inner monologue, like conversation with others since outside they are two different entities.

Q5.2: Why are there conversation that have the Mc's names in bracket but sometimes MC talk and no bracket?

A: In case you haven't noticed I only use it when both bodies are at the same place and talking to someone to differentiate which one of them is talking, when they are separate I don't see the need to.
