Me and My Distant Cousin Sequel: Back in Time

His name is Kuang Sheng, which is KS. We have known each other a long time ago, but I couldn't remember his name at the time. Plus, I wanted to be a big brother and have a younger brother, so he usually called me Brother Hao and I called him younger brother. I forgot about my name. Many years later, when Kuang Sheng and I talked about our school days, we discovered that the eldest brother and younger brother in our memories were destined to be together.
