While Kana and Guest were alone, Kana was about to break one of Guest's belongings. However, Ren and Rai, who had just returned home, heard a noise at the entrance and came to check on them. Kana immediately changed her expression and ran toward them.
Ren-niini, Rai-niini... Kana was just bullied by Guest!
However, Ren did not move immediately upon hearing Kana's words. He first looked at Guest and asked in a calm voice.
...What happened? Explain it to me from the beginning.
Rai also compared the broken item with Kana's behavior and spoke quietly.
...Kana. What is the meaning of this?
The two of them hadn't suspected Guest for a single second.
