Plss maga title help

Does anyone know the manga where they’re twins. The older sister twin is dumb, she’s not but she’s seen like that because she’d often be compared to her younger twin brother is good at everything. They always fight but they both care about each other and have good character progress. They have a girl childhood friend and along the way, they made good friends. The sister twin got a situationship(idk if they got together) with the pastry guy (year older), who later moved abroad to pursue his career. The guy twin got together with the childhood friend. I think the title has something like “clock”? Or “time”???? It’s mostly focused on their sibling dynamic.
