After Crossing the Delta, All the Female Operators Are Attacking Me

I traveled to the Operation Delta theater and became an observer who shouldn't exist. My mood swings will be directly reflected to the four female operators. My heart beat faster, and their fighting power surged; I was heartbroken, and they felt the same. Hafk's lightning blast, G. T. I.'S intelligence blade Luna, the ghost claws wandering among the codes, the white dove butterfly on the battlefield—— They thought I was just a bug who needed protection. But they don't know that every time their heart beats faster, it's all because of me. This novel and its characters are purely fictitious.
