Guys can anyone of you gimme a recap . My head not working

Jake is top secret government agent who is in the mission to collapse some big gangs from inside. Shingun doesn’t know this. Shin ruined Jake’s recent undercover mission (in the car place) because Jake chose to protect Shin againts gang members. Shin didn’t know Jake was there but seing how the events took place he now understood Jake is not some gang member and angry+confused about knowing nothing about Jake.

Anyone feel free to correct me or add more o/

Wow that’s crazy! Thanks
