I started wondering where all the Youtube Poops and TF2 videos got the amazing music they used for their remixes, so I looked it up for a bit
Soul Eater wiki mentioned how the frog bitch looked sorta like Suwako, looked it up a bit more
One of the captions on TFwiki mentioned Danmaku, I looked it up and it brought me back to Touhou
This all happened around a similar time so I just kept wanting to know more about it and looking it up and eventually I downloaded EoSD, and it was smooth sailing from there
Years ago my sister showed me Marisa Stole the Precious Thing, and I had a phase where I just listened to Bad Apple, but I didn't know they were from Touhou until way later
You should have seen my face when I was playing stage 3 of PCB, I was all, "Hey, I heard this before, I swear I did!"
