Pov yang
Location interrogation room
Yang: you know boys usually don't run away from me
Lark: you're not that hot
Yang: now you're being insulting
Y/n: mr.lark...why did you try to run?
Lark: ...when federal agent get at your place you get nervous and run
Yang: did you know that Velvet and Cardin still banged?
Y/n: I'm not quite sure you should say it like that agent Xiao long
Yang: y/n, your help is very appreciated but not needed here
Y/n: should I remind you that your superior requested me as your partner
Lark: look, your love quarrel is hella cute but I've hot things to do
Yang: not until you tell us why you ran away....or tried to run
Lark: ok, me and Cardin were doing drugs back when he was alive...and not the legal Kind
Yang: there is no drug that is legal outside of medecine...however we found illegal drugs on his body, here's the deal, you tell us who got you these drugs and we can strike a deal...was it Velvet?
Lark: KEEP MY GIRLFRIEND'S NAME OUT OF YOUR GODDAMN MOUTH
He tries to punch me, but I grab his arm
Yang: would you look at that, i hit a very sensitive spot
Lark: it's true, I love Velvet...and I did ask her out, but I respected her choice, Cardin was my friend, my best friend, I would never hurt him...especially just for a girl
Y/n: you seemed quite angry when agent Xiao long suggestive that " just a girl" was selling you drugs
Lark: Velvet was cheating on Cardin with me, we had a secret relationship, if you want à real suspect, go find Ruby rose, I saw Cardin and her argue and fight
Y/n: we'll investigate, agent Xiao long, would you kindly follow me outside ?
I nod and we leave the interrogation room
Yang: you're not seriously thinking Ruby killed Cardin? Right?
Y/n: we already know she did not, but I want to know something
Yang: let's go then
Y/n: not you, you are needed here, besides if she did do something Wrong, she might hide it out of fear of disapointing you
Yang: and what about Lark?
Y/n: he is guilty, he's nervous, he had the mobile of the crime, the drug that weakened Cardin, and despite what he Said he's quite obviously guilty
Yang: I can't arrest him based on that y/n, the dagger used to kill the victim had no DNA except cardin's blood
Y/n: what dagger
Yang: oh yeah, I didn't tell you, when you went back to your dumb school, we kept working, and found out the dagger
Y/n: why not tell me?
Yang: because you probably wouldn't have cared since it was during your classes
Y/n: are you mad at me?
Yang: why would I be, because you have 3 jobs despite making a shit ton of cash, or the fact that you barely seem to care about this, since this case was open you barely took any intrest in it...why?
