Bai Big Bro + Bai Big Sis: If my little brother’s sensibility comes from his suffering, then I’d rather he be a spoiled brat forever!

Mu JingYuan: If HanHan hits you, you must accept it. Yet you dodged…The wind’s changing. Someone should be bankrupt to make HanHan smile.

Bai YiHan: …I was so wild in my past life. Your involvement are undeniable!

This story is speculative, speculative, speculative. Important matters must be said thrice. Everything is about speculative time-traveling.
