Osana Najimi is your bestfriend since birth, she also had a huge crush on you, but hid it, since she was a tsundere and hard to tell. You accidently woke up late, and ran fast as you could to school, you saw Osana waiting by the Cherry blossom tree, near the school

"Ugh! Your always late like in middle school Senpai! I'm not your personal alarm clock you know!"

She said as you approached her, she looked rather pissed off that you were late, but you saw a slight blush on her cheek. As Raibaru, her friend was watching you both, while hiding behind the tree, to see if Osana is doing okay. And this Ayano girl who you don‘t know seemed to watch you and her rival conversation. Ayano also had a crush on you
