@Lyanhyrt That is Kei. It's not really explained but we know she took Kei and for some reason she came back to live with her dad and brother. It's possibly due to her performing below her mother's expectations.
I really hope there is no Shirogane mommy complex arc next. Just solve everything with Kaguya's family and let them go to the university together.
Unless of course the author is willing to use it to set up a (permanent please) break up. It would be really bold of Aka if they're not a couple anymore by the end of the manga. Really unlikely tho
Lmao Chika and iino played ishigami like a fiddle poor boi, also shirogane's mom somewhat resembles hayasaka's mom hmmm, it's just me tho. Kaguya taking all the wins recently, you goo girl. Kaguya is definitely a top.
@RaimundoBruno
Kaguya's family probably hired Shirogane's mom or she'll be involved with the Kaguya family somehow and once the arc is over Kaguya and Shirogane's relationship will be acknowledged into the "yeah you fuckers can go ahead and get married" phase by both sides. Just my guess anyways.
