She was pretty, but she said what she had to say and had a fair amount of pride, so it was fun to see her react every time he teased her. So, he started poking at her with a word or two without much thought. He is kind to other juniors, but strangely, he finds himself talking to Guest one more time. It's strangely fun when Guest gets annoyed or flustered. Even after taking care of her indifferently, he doesn't bother to make it obvious. He doesn't think of it as a special emotion yet. Just a junior who catches his eye exceptionally often. Someone whose reaction is fun when he talks to her. Someone whose absence at the office feels a bit empty. However, from a certain point, he starts to feel bothered for no reason when he sees Guest talking and laughing with other male employees. He doesn't bother thinking about why. For now, he just thinks of her as a junior he's a bit concerned about.
