Shinope: Stay away from Sakura Sakine, she is dangerous.
Chiyoko: Turns out, Sakine is a good person.
Me: Are you stupid? she just gave you a dissertation as to why you should not trust Sakine.
I am not entirely sure if Sakine bought the "friends" part. She got mad when Mafuyu said that Chiyoko was her slave.
Also at the end, it appears that Sakine sees Mafuyu as a nuisance and will play with her to make Chiyoko sad.
Not sure what the plan is, make Mafuyu fall more in love, dump her, Mafuyu bad end, and then she gets Chiyoko to herself by playing the victim.
Anyways, Shinope best girl.
