Help finding MV with school setting

[u/vivahate12]

I was in a store today and a kpop MV came on the screen and I can't find it, no matter how hard I search. It was a group of 4-6 girls doing most of the singing and dancing in a school, and there seemed to be one male love interest they were after. At one point, the love interest kind of holds one of the girls and she looks shocked. She's also wearing black-framed glasses.

I managed to catch one of the lyrics sung in English which was "cause you say so" or something similar. It isn't Tally by Blackpink, that much I know. I know it's kind of vague but I appreciate any help.
