I'll be honest, i skipped all the chii chapters because i wasnt interested in her arc, can someone fill me in on the hate for her? Last i remember she was just the gremlin of the trio that everyone liked.
Well, you see, Chii-chan was kinda like a manipulative gals. Among the trio, she was the most insecured, confused, and anxious one. Her bestfriends starting to work harder for their dream and futures, while she was stuck in limbo, didn't know what to do with her future, and prefer to stay as a high school girls to laugh, giggle, and have fun. Basically, the kind of person who lived in the present.
Not only that, she also hated change. She awared that Tokio had feeling for her, but she choose ignores it, didn't acknowledge it, and prefer to stay in the status quo. She even leading him on, just so she can have fun. Quite selfish, if I had to say.
Now then, it seems the author were cooking for Chii-chan's drama, but I don't know how they're going to handle her character development. The peak is probably when the setting reach around autumn or winter when Anjou, Toyoda, Tokio, Seto, and Inuyama get even busier with their exam prep. This chapter already showed how Anjou and Toyoda were a bit reluctant to hang out and prefer to keep study, but because Chii-chan insisted, they ended up folded.
