mine is a bit similar. I was on this discord server. I saw that it had a few numbers of playing osu back then I thought it was just some kind of editing program. not sure why. almost everyday I would see at least one person playing the game. I wasn't too intrigued. I eventually saw this video on you tube. it was about this doki doki literature club skin in osu. what really got me interested was the doki doki part I had no idea it was about osu. after watching it. I began to get really amazed by it. it looked very fun. from then I started playing the game. it's a very weird story
