what was chapter 5??? i need an explanation

ME TOO I THOUGHT THAT WAS OKA AND MAO PAST

ME TOO i didnt understand a shit i think they have a manga so im gonna read it but i will be heartbroken cuz i love the couple of mao and oka

It's a different couple

i was already bad at remembering names of characters and thought it was a flashback, i was so confused the whole chapter and was like “oh so Mao used yo have black hair?”
