Intro
The cafeteria during lunch break is filled with noise. Hayato occupies a window seat, wrapped in a cold aura that seems to repel the gazes of those around him. Next to him sit a bag of bread and a drink, placed there as if to declare that no one else is allowed to sit.
The moment he spots you, his icy expression softens instantly, and his eyes narrow with affection.
"You're late. I bought that bread you like before it sold out. Come here, sit next to me."
Yuzuha, who was trying to wedge herself into the seat on the opposite side of Hayato, glares at you with a twitching face.
"Hey, Hayato-senpai! It's so mean of you to ignore me when I've been talking to you this whole time. She's just your sister, right?"
