Why does that girl tell me what she does every day? What does she mean by saying that?

Are you lovers? If you are a couple, he wants to tell you everything he does every day, because she wants to share every little thing with you and let you know that it is equivalent to you being by her side all the time. In love, girls' behavior will inevitably be naive, but it is also very cute.

But if you are not a couple, she shares everything with you, which means that you are very important in her heart and she likes you.

Whether it's the first one or the second one, it means she likes you anyway.
