mister prosecutor i trusted you!!! all men do is lie

what did he do? i'm lost D:

He said he didn't find anything in the locker mungryong told him about that's related to his sister. But in the next panel, the seme's men found out that the prosecutor's assistant took something from a locker. So mister prosecutor is lying to our uke :/

I think he lied to him for like, protect him or something like that. Even tho I’m sure Mongryong can smell the lie and won’t be happy about it haha
