Lmao aww look at her feeling left out. It's annoying and amusing to see Chizuru lash out like this. From what we've seen so far, she's been a self centered individual who's been dismissive of anything she not interested in. It's attitudes like that, that make people feel unvalued and kills friendships. Your friends don't need to share every one of your passions or hobbies. It always puts a smile on my face to see friends or family get excited and talk about something they're passionate about. Mao seems to be stuck in the middle, dragged around by Chizuru.
