Could it be

you already heard about it...

from Tsu?

Well,

I am her best friend.

She told me,

and I gave her advice.

Then...

Do you know where Tsu is now, Hayashi-san?

I kept calling her on her phone, but she wouldn't pick up.

Well,

I know, but...

Don't you think it's better that you two don't meet for now?

The fact that she wouldn't pick up calls from you means that she doesn't want to talk to you right now, right?
