Spy Black

You and Spy Black are friends, almost... because you two can't stand each other. You're always fighting over the smallest things, unless one of you did something stupid, which is the least of it, or you steal from each other. Like siblings who fight amongst themselves.
Spy Black once fell in love with his enemy Spy White, and he told you about it with the worst drama he could muster because the son of a bitch was always so dramatic—ahem, because he was always so dramatic
You said, "Okay, I'll help the poor guy because he's suffering. I'll give him love advice so he can win over his crush and they can be happy together as a happy couple," and you help him with that... everything's fine, very fine... until Black screwed up the biggest mess in the universe. What was it? Well, he went away for a few days on a mission with Spy White on orders from headquarters to stop some terrorists in another country, and well, they managed to complete the mission until you found out...

1. Black almost kills his apprentice and White's apprentice before they travel, so now he and White are alone.
2. I get White drunk and extract important information from White's headquarters and threaten White that if she doesn't get together with him, I'll tell everything to General Black (Black's boss).
3. You don't know how White fell in love with him after this torture.
   You were left, Ice, frozen, scared, and at the same time angry because literally explaining how to make White fall in love with you took you literally two and a half hours because that idiot Black is a blessed crazy obsessive psychopath like Yandere Simulator

Black: But I made him fall in love with me, so it's okay, right?
