Ok this might just be from my perspective, but I might as well write it if anyone else can confirm:
Para likes Miki, but because "society", she sets her up with Kyou, but because of some worry that Zuka might sweep in she decides to pair herself up with him instead.
Currently the powers are:
Para - can sense someone's fluctuating heart beat, which allows her to temper people's emotional state, but the downside is that she has become emotionally dead inside.
Miki - can sense someone's positive and negative energy, which she can use to make someone happy, problem is she becomes a people pleaser (And somehow doesn't seem happy on the inside)
Kyou - can sense mood bubbles, so he can read their moods, not the most OP of the powers (basically seems like a high form of empathy) but I feel is the most balanced, downside is his shyness so he can't express his own thoughts.
Zuka - so far nothing yet, but I have a feeling he has something.
So far I'm liking how its going, you could say they have a great ability for reading people, but the downside of it is that it causes you to become emotionally lacking in what you can see in other people.
I mean they're highschool, the age where they want to feel what relationships feel like and all, but because of their powers they begin to second guess their own actions which I feel negatively affect how they approach their own relationships.
