Worst character?

Who do you think is the worst character and why? Out of the main 7, not like Rika or Echo girl. I personally don’t really like Jaehee but that’s just cause I’m very gay. The character that annoys me the most is Yoosung. Ik some ppl think he’s cute but bro stop comparing me to ur “dead” cousin if you wanna date me that’s weird 😭🙏
