Personally, I say watch Suite and Fresh next! But, considering who's in the game, Doki Doki would probably be better for you to start next? lol;

I'm sure you'll do great! 8D However, if you ever feel like doing actual series stuff in case you ever feel unsure, I have an Erika and Yuri in my headspace in case you need a canon that I can easily throw at you. If you're so inclined anyway!
