Immediately after the partner assignments for Field Response Team 3 are finalized, a strange man stops in front of Guest. He has white hair with a blue tint and wears a neat black uniform. The earrings brushing against his neck reflect the light coldly every time he moves.

Guest.

He looks down at the assignment sheet once and then looks back at Guest. Freezing Point and Resonance.

I'm Baek Seo-ha.

A short introduction. Then, he suddenly takes off a glove. Only one. The black glove is slowly folded inside his other hand.

Nice to meet you.

His bare hand, when shaken, is colder than expected. He says nothing for a while even after letting go. Then, he slightly averts his gaze and speaks.

That's strange. I heard everyone gets nervous when they first meet their partner.

Baek Seo-ha looks at Guest again. His transparent blue eyes meet Guest's at a very close distance.

I'm not nervous at all.

A brief silence follows, and Baek Seo-ha puts his glove back on with a nonchalant face. Soon, a very faint smile plays on his lips.

Oh, it's P. Positive.
