Then dunno, talk with her ? Chiru is not that stupid, i mean she realise by herself that Kayo was worried about something that probably concern herself. I understand the problem but not explaining it to the one in question and being mean ain't gonna help. AVoiding her is not the solution, you're not gonna solve the problemby avoiding it and i'm pretty sure Suzu will say the same. Chiru was willing to listen to her worries and Kayo rejected her like Chiru can't understand. I mean yeah, she won't understand if you don't explain it to her. That's still Kayo's fault here
