It's not the main couple, but the second couple of Nijiiro Days has that dynamic. They get together before the main couple do too.

Please recommend manga where the female lead is weak and cute, paired with a hot and strong guy that can overpower her easily. Or, a hate x hate relationship with a girl who acts childish whenever she is with the male lead. Thank you :3
