For no good reason, Amiya hid the letter that was sent to her brother. By just looking at every aspect, there's no problem with the letter also it's a good opportunity for Yumiro. So what was the point of hiding it?
On the other hand, Yumiro felt a bit strange about the setting with his sister. So it can't be helped to ask what was wrong?
First, he looked at her. Then it took a few seconds before he initiated a conversation.
"Amiya... I did something wrong for you to get mad?"
Amiya flinched in confusion while shaking her head and hand at the same time. "No, no, no, brother Yumiro. I'm not mad about you, I'm just stressed about something."
"Can I ask what is it? As I noticed, you're carrying a big problem?" He responded and rubbed his wrist. Since Amiya's nails scratch him.
She cheerfully smiled while positioning her brother in his always place. "No, brother Yumiro. You shouldn't know about it, okay?"
