Ino and Sakura used to be best friends. It was both their crush on Sasuke that drove them not to hate each other but to drive them to be better than the other. Like you heard them say, they're rivals but deep down, they still care about each other.
Fun fact about decibels if you didn’t know: it’s not like meters or minutes that’s scale on a geometric rate. Decibel scale on a logarithmic rate. For every 10 dB sound is , its intensity increases tenfold. 30 dB is 10 times greater than 20 and so on. Bottom line, sound can be dangerous lol. Also say goodbye to long-haired Sakura because her hair is gonna remain short for the entirety of the series
