Prompt: disoriented
Rin loved a good argument. It cleared her mind and made her feel incredibly pleased with herself. She was aware that it had different effects on other people, but that wasn't something she thought about particularly often.
It was possible that she should have.
Of all the people she knew, she argued with Issei the most. Or really, he argued with her, and she calmly put him in his place.
It was in the middle of one such argument that they both realized something. Several things, actually.
One: as sometimes happened when people argued, they were standing very close to each other. So close that their noses were almost touching.
Two: as sometimes happened when people argued, Issei was breathing heavily, heart pounding so much that she could hear it.
Three: he was also looking at her with wide eyes, as if he had never actually noticed what she looked like before. Knowing him, that was probably true.
Four: they were still very close to each other.
Given all this, she really should have been less surprised when Issei muttered, "well, at least I won't die without-" and pressed his lips to hers.
It only lasted a moment before Issei backed off, apparently having come to his senses.
An awkward silence ensued.
"Th-that shouldn't have happened, that didn't happen, and we will never speak of this again," he finally said.
Still shocked, Rin could only nod in reply.
Issei made a hasty exit, but paused just before leaving the room and said thoughtfully, "…I guess you're not poisonous, after all."
