That might be a normal person's reaction. But for those who are already involved in different things, it's easy for Fuyu. Aki who stays and permits directly in front of his father. And everyone at the table knew their relationship was very special.
Aoba must have understood that Aki was a bit displeased with his presence. They seem to be betting when they face each other. And honestly, Fuyu doesn't like it. He also hastened to eat. Suddenly Fushimi said 'maybe' with a smile before the activity disbanded not long after.
Fuyu immediately approached Aki as soon as the two of them had entered her room. "Why did you act like that, Aki?" he asked.
"What why?" asked Aki back.
"You hate Sis Aoba, don't you?" Fuyu asked.
"Not really," said Aki. Her lover was lying on the bed staring at the ceiling. "There's no reason to hate him. So why should I?"
"That's not it, I mean that—"
"Fuyu," Aki called.
