Broken Base: Some readers have mixed feelings about the idea of the plot with Yui having so many children. Some think it's a little risky since that means too many characters to keep up. Others love the plot since it means it helps with the ship wars.
Ensemble Dark Horse: All of Yui's children are getting love from the readers due to their innocence and other personality traits, and just being very cute.
Jerkass Woobie: The Sakamakis, Mukamis, and Tsukinamis are this like in canon.
Unintentionally Unsympathetic: The Sakamaki, Mukami, and Tsukinami brothers. Well, they came to regret how they treated Yui in the past and were horrified to know that they raped her, it doesn't excuse their actions for all the pain they put her through.
Win Back the Crowd: Many readers love the story since they feel that it's refreshing to have an actual fanfic story where Yui is treated like the heroine instead of an OC who steals the spotlight from her, and having original characters with flaws.
Woobie Family: Yui and her 22 children are this. They have been made fun of, due to Yui having so many pregnancies and having kids that look nothing alike and the latter without any of their fathers in the picture. The kids themselves have been bullied by their peers for not having fathers. To make it even worst, the whole reason their family even existed is that the children's vampire fathers raped their beloved mother, which is caused by their grandfather who drugged his sons and Yui having PTSD.
