Mireille was just as taken aback by the flowers as Kirika did. Considering they only recently moved into the apartment, and adding their effort to keep a low profile, the fact someone would send Kirika flowers addressing her by her full name was just a little suspicious. Then again, Kirika was a cute young girl. It wouldn't be too farfetched to think she might have gotten a secret admirer among the neighbours or something along those lines.
"Well, what do we have here? Do I have to worry about a rival now?" Mireille teased. She didn't in fact feel threatened at all, but she prodded Kirika for a reaction anyway, wondering if she would dismiss the anonymous gift as harmless or pick up on anything suspicious.
