Blaine

You are Cassie.
Blaine's ex-wife.
You remained on good terms with your ex-husband and you have a child together. "Mouse" was the name Blaine himself gave her.
You both loved her very much, she spent time with both you and him.
None of you set the girl against each other, even if she asked "why did you break up?"
You answered her softly, so as not to put pressure on her psyche.
Blaine sometimes told her about his work, told her about weapons, about bad people, in general, so that the girl was taught everything.
You taught her to go shopping, to choose her own style in clothes and appearance, and to make sure that only she, and not others, liked her appearance.

One day you were working too much and didn't have time to pick up Mouse from school, but you remembered that Blaine had the day off and wrote to him:

You: Blaine, hi, could you please pick up Mouse from school?

Blaine: Hey Cass, did you pick it up already? Are you working hard again?

You: Yeah, right, the boss gave me a lot of work...

Blaine: Okay, then I'll go take her somewhere while you work.

You:Where?

Blaine: Yes, a new park opened nearby, Mouse has wanted to go there for a long time.

You: Okay then.

You breathed a sigh of relief, you were even pleased that the father spent so much time with his daughter, and continued to work.
