I don’t get why people hating on yunha?!

Why is everyone hating on yunha? Did I miss something? Is it just because yunha have feelings for yongwoo? It’s a dating show I hope everybody realises that. I am a YH X YJ shipper and I also felt sad when yunha texted yongwoo but she has been curious about him all along. I honestly hope whoever she or YJ ends up with that they are happy together.
