Be My Princess: PARTY [Roberto Button's Walkthrough]

This walkthrough is for Roberto Button from Be My Princess: PARTY, and note that it is not for the paid or GREE versions. 

Please note that the following walkthrough is for after the common route. Apparently, the common route does not have any affect on the chemistry of any princes. So, need not to worry. I suggest using gems to pass through the sweet routes of avatar missions, so as to get exclusive illustrations. Lastly, this walkthrough will help you to gain at least 100 Chemistry points to get to Happy Ending and you'll need at least 72,000 Royal Factor to get to Secret Happy Ending.
