The first day of the month is a busy one. And one which may take some time. Be sure to save before starting today’s activities, ‘cause there are no less than three random events which should take place today. If any of the three following events does not take place, load the game and try again. It’s important that your Passion is at 99 at this point, but I doubt you’ll have any problems in that area.
First, you should meet Chiemi again in the park. Tell her she’s feminine.
Second, you should find an envelope from the God of Luck containing 10000 Yen, and meet Arisa right after. Choose to hang out with her for a while. When she asks, say you don’t have a girlfriend yet. You should also walk home with her.
And third, in the evening you should find a kitten seeking shelter from the rain. Take pity on the kitty (oh, that sounds nice ;) and take it home with you.
