>>17179696don't worry about not knowing every single suisei related detail bud, if you like her so much then that should be enough. obviously don't talk about shit you don't know or have no idea about, but that should be common sense; you can always ask or do archive reps when people start talking about things you're unfamiliar with. besides, like that other dummy said, just buying her album already puts you over a good chunk of the fanbase lol.
but to answer your question, i guess you can watch as many VODs or clips as you want, though personally i'd start focusing on keeping up with her right now, maybe a few months back if you really feel like it (assuming you have free time). some anons here have asked "what's your favorite suistream?" before so maybe you can use that as a starting point too. that documentary you mentioned is pretty good as well in my opinion.
anyway enjoy suzy!
