Specific Klaine fic - Blaine is Kurt's daughter's teacher

I am looking for a specific Klaine fic. Blaine was Kurt's daughter's (I think her name was Hailey) elementary school teacher. One night Blaine is at school late and I think Kurt goes to bring him dinner. Kurt's ex (I think) shows up and ends up shooting Blaine. The school janitor calls the police. Kurt blames himself for Blaine getting shot.
Thats all I remember and I may have mixed up two fics...I just can't find this classroom scene.
I've tagged my post, but it doesn't seem to show on the preview so I'm sorry if the tags don't come through!
