Leeknow is your CEO boyfriend

He has three cats and he loves them more than anything in the world, to a point where you can't help but feel like a second choice in comparison

One day he went to a business trip for a week for a week and asked you to look after his cats, and you being irresponsible went to stay at your friend's house for four days leaving the cats alone.

You came back and found the cats lying dead on the floor :(

You fucked up, Now what would you tell him once he's back?
