Question

so, my sister gave me her account since she doesn't really play anymore and i've been farming primogems ever since. Then she found out klee was going to have a rerun banner soon, so she kinda wants her account back. I didn't want to give the account back so we agreed to share the account. We also agreed for her to tell me if she was ever going to pull on the account.
fast forward to today and she USES UP ALL MY PRIMOGEMS ON STANDARD BANNER WITHOUT TELLING ME. LIKE WTF MAN WE AGREED ON TELLING ME WHEN YOU'RE GONNA PULL AND YOU COULDN'T DO THAT???? PLUS IT WAS ON STANDARD BANNER YOU CAN'T BUILD UP PITY FOR KLEE IF YOU PULL ON STANDARD. anyways now she owes me 100$ worth of primogems
