"Senpai, why are you with that girl from Kaihin yesterday?"

It's just a casual conversation among the peers in the Service Club Room when Isshiki suddenly dropped a hazardous bomb.

My eyes widened at that statement, her ramblings makes sense now. I briefly looked at my club mates and both of them were shocked.

"What is she talking about, Hikigaya-kun?" Yukinoshita asked, her voice indicating that she demanded an explanation.

"Y-Yeah, Hikki!" Yuigahama, don't also give me that questioning look.

"S-She's only my old friend…" I replied, but they didn't seem convinced.

Run.
