You're not alone. I keep checking the new chapters, hoping that this one will be the chapter we're finally done with her. A few of the gags with her have been mildly funny, but the joke of "haha, she's an uncontrollable s3x doll" stopped being funny after two or three chapters.
Keeps hinting at a love triangle between the guy and the sisters which while cliche would be on brand for a rom com, but this whole student council arc just feels out of place. I honestly don't even remember why she wanted to be pres in the first place and it certainly doesn't feel like there...
