As i Promised to myself, I'll start playing JPDori if I get Lock in like 5 resets

WELL AS IT TURNS OUT I GOT BOTH CHU2 AND LOCK IN MY FIRST PULL, AND BEFORE THAT I GOT THE 4S CHU2 IN THE FREE GACHA, SO I'M PRETTY HAPPY NOT GONNA LIE

After all this hype, is there any form to "link" your account to something? i don't want to lose this account, thanks ^^
