>>280809388The NBR thing.
Remember Seiha was harassed.
If John Lennon spills the beans to his dad. Shiunji's truth will go viral on internet, and all the siblings will get harassed for that, then you'll have the NBR siblings grow hateful at each other, then Kotono sticking with Arata bc she obsessed... until their blood relationship gets revealed and shit ends hitting the fan.
The end may be the siblings living their separate luves, Arata taking over the remains of the Shiunji estate and being thrown a bone by ending with bun chick (he shall thank Ouka for that... someday), and receiving a letter from 5 girls.... despite of not having names, he can identify who's who because of the way they write, him realizing that no matter if they aren't blood related, the bond they share can't be replaced and knows deep down, they all have forgiven each other. It all took Arata discarding himself from the bowl...
But that's what Arata wants to avoid.
