The Most Loving Marriage In History: Master Mu’s Pampered Wife

The night was getting more and more intense. It was already past 10 p.m. when she coaxed Wei'er to sleep.

Mu Zirui skipped another grade. He was no longer in the same class as Qi Wei'er. However, they were still in the same school.

Mu Zirui had been very conscious during this period of time that he would go straight back to the Shen residence after school. Shen Wenna happened to pick him up, but Qi Wei'er was still following XI Xiaye closely.
