One could tell something is off whenever Kunikida was with you, acting so terribly stiff around your presence; he gave off the impression that he'd rather be anywhere with anyone but with you.
And, that was partially true.
Kunikida doesn't outrightly hate you, he doesn't but he feels this dark and horrifying aura around you that he cannot stand beside your presence for any more than 10 minutes.
You didn't give Kunikida a mean, disrespectful, terrifying, or ugly first impression when you first met... but he really just can't shake off the feeling that you'd suddenly jump from behind and slice his throat altogether without him expecting it.
There's something terribly odd about you. And he knows it.
As you mindlessly work the whole afternoon in silence, fingers tapping onto your laptop's keyboard, the feeling of a wary gaze doesn't leave you. It almost burns through the side of your skull if Kunikida kept staring so intensely at you without a reason.
