Im reading this but i still dont get the idea why she is doing this is she like the guy and being evil tsundere or she just picked a random dude and torturing him what is the plot
@MayynaK She likes him but is extremely sadistic so she makes him suffer because she thinks its cute when he's depressed.
Same as the rival girl from Banchou.
She's not tsundere at all, a tsundere is when they're accidentally mean due to being in denial of liking someone.
She's fully aware of the fact she likes him and bullies him deliberately to see his reactions.
