Just because she puts a wall up because she's justifiably scared of being stabbed, dances slowly and with great pain to her body because she has asthma, and is shy around people, doesn't make her a bad person. It makes her human, a good human who despite her fears of being harmed, despite the physical pain she endures when dancing, carries on and does it anyway. Why? Because she cares. She cares about her fans, and being an idol, and she cares about her friends. Who might her friends be, you may ask? Not dirty women, or scandal girls. But the golden hearted angel Yuihan calls Paruru her friend.
Birds of a feather flock together, and Prr's flock is as good and blameless as you can find. Look for another girl to slander and irrationally hate
Paruru is an idol. She isn't strong in body. She's small, she's weak, and she has asthma. She isn't strong in mind. She isn't smart, she's shy, and she's fearful. But despite this, she accompanied her friend to the audition. Not out of selfishness, but to keep her friend company and she was unexpectedly, almost against her will by fate, selected to be an idol. "I'm not good enough" she might have said "I'm shy, I'm weak, I'm afraid" but despite this, she took up her burdens and did the best she could. For her fans. That's why she still goes to handshake events, opting to put up a wall rather than stop going altogether because she knows her fans want to see her even if she's scared if being stabbed. That's why she performs, despite her asthma and despite the danger that she could pass out and die with every step she takes just so her fans can see her dance. That's why, even with all she has going against her and all the reasons she has to quit, and all the times it must have crossed her mind while she was standing on stage, her chest tight, struggling for breathe, she hasn't graduated. Because even in those moments when her vision is blurred from lack of oxygen, the only thing keeping her going is the thought of not letting her fans down
Being an idol isn't about being perfect, it's about putting in effort and overcoming your weaknesses. Paruru is an idol and she cares about her fans, and if you have a problem with her you have a problem with idols
