Need help

manga or manhwa I can't remember

scene at a masquerade ball at an academy or smth of the sorts where girls high heel gets stuck in a crack while in a broken pathway of the academy grounds and male lead helps her get it out and fireworks show starts and the girls and boy ends up seeing it and then after it ends the ML disappears

and I think if I'm not mistaken before this the mom says smth like you're too young for high heels
