1V1 hehehe
Cheng Shengjia and Xiao Lei are not brothers
Cheng Shengjia is a police officer and Xiao Lei is a sports student at school.
Xiao Lei's parents were firefighters and died in a mission.
Cheng Shengjia's parents adopted Xiao Lei
So two people under the same roof become the most untouchable part of each other.
Cheng attacks Xiao Shou!
Intention: Hard work and persistence will be rewarded
