Roses for Cassandra

I'm... really busy! I'd like to give out some chocolates and roses to spread joy and make people like me more, but I am SO busy that I don't have enough time to get the roses!

So, could you do me a favor? Could you please help me by getting roses? If you help me, I will give you some chocolate in return. And if you help me more often, I will give you even more!

Perfect! Okay, take this seed and... um... wait? I think that's how it works. Maybe like 30 minutes, I guess. When the seed turns into a bloomed rose, bring it back!

Really? Well, when you want to help me, talk to me!

The rose has not bloomed yet. You have to take care of the Mysterious Rose Seedling for 30 minutes!
