Of course Kuroki-san would freak out when you talk about rings all of a sudden...

Why don't you try changing it to some simpler accessory?

For example?

How about a hair tie?

*As seen through Katou-san's filter

Giving Kuroki-san a hair tie...

But if I do that she'll be too sexy and the boys will be looking at her in a lewd way!

Think about this seriously, Kaho!

Just do whatever you want, Asuka.
