Make it up to you

Jeniffer: I can't believe you Ben. I waited for your call all night. Why didn't you call me?

Ben: That's what I came here to say Jen. I fell a sleep on my couch. I'm so sorry.

Jeniffer: What a lame excuse. And it's easy to say sorry.

Ben: I know. Let me make it up to you. Let me take you to dinner tonight. What do you say?

Make it up to you: To do something good for someone you have upset, in order to become friends with them again.

"Them" can be used to refer to him or her when talking about somebody, regardless the gender.
