2 days into playing the game with some random office mouse, I decided to try using my mum's wacom ctl 4100 she used because of her RSI from using a mouse. Since then she's moved on to a fancy trackball mouse, so I guess the drawing tablet is just mine now. This'll be real ironic when I have RSI from playing too much osu in 4 years.
Since then, I've gotten a 144hz monitor and a mechanical keyboard after just using a laptop for a while, not specifically for osu, but because I wanted proper peripherals to prepare for an eventual pc build I mean for online class yeah definitely for online class (the extra monitor was super useful though, I don't think I can go back single monitor setup).
