Multiple heroines, urban fantasy
I awakened my superpower, but found that it was "emotional synchronization". Once my mood fluctuated, it would be shared by those around me.
The cold-blooded captain: "You secretly stayed up late to watch a show yesterday, and you were calling me wife in your dreams?"
The yandere senior girl's fingertips were twirling my hair: "Senior, my heart beat two beats faster when I was attracted to that girl just now."
The seemingly weak librarian used a copy of "Advanced Mathematics" to suppress the monsters on the street when he went on a rampage.
They all thought they could easily control me, a newbie.
Until I lost control and synchronized the despair of the whole city, and they heard my calm heartbeat in the shared fear.
