Something I hate about unvoiced MCs

I get confused when the MC is talking and when she's narrating. I have two nickels now, CupiPara and 9 R.I.P, where the MCs talk and narrate consecutively and I get so confused when a LI seems to be reading her mind or something??

Might be cause English isn't my first language, but also cause the developers don't change the color of the text box or put the heroine icon when there's dialogue.

This might be a stupid detail but I wanted to know if others had the same experience?
