I feel like that ranking is exactly how it should be, for the main four. Perfect order. Marika belongs at the lowest end for her questionable methods. I appreciate her spirit, but I cannot forgive or condone her conduct. I respect that she honored certain principles with her pursuit, such as keeping secret on the fake relationship even though she saw right through it (realized the relationship was an act, but not the feelings)... but many of her acts felt far too overbearing and unpleasant, to me, and I just cannot abide.
Anyway... Finally, Chitoge is where she belongs at number one.
But not in this chapter. I mean, I had a feeling something like this was going to happen. I had a feeling there would be one last crisis of conviction like this. That Kosaki would somehow express her feelings first, in a way that at least Chitoge would overhear.
Chitoge is a good friend. She's going to feel like she has to back off, even tough that means giving up on her happiness. But Kosaki will ultimately not let her, and neither will Raku. Because that's the only way it has to go down.
This is my prediction, anyway.
