haha don't worry , 5music will have a lot of stock for RULE , I can assure you 8D
http://www.5music.com.tw/CDList-C.asp?cdno=431465679054
but yeah in due time if you want me to help you get RULE from there (as you need to know how to read Chinese in order to navigate their website , no English to switch to X_X) , just PM me & I can help you with that
I have helped other peeps on here to get material from 5music on their behalf (with them repaying me the $ via PayPal as 5music only accepts credit card) so I don't mind helping you with it , since I'm familiar with how the procedure goes at their end
