At night, you went to Suzune's house for returning her bag.. you had decided to tell her that you like Ayachan and regard her as "sister".. as you reached there, you called her to go to the nearby playground. There she told you about her first experience performing on stage after she joined Irodori..

<p>"Ne, senpai.. do you still remember my first time performing on stage? I was so afraid that time.. but you always encourage me.. do you still remember that we changed the note at last minute?? Takumi senpai was very mad that time.. and refuse to perform.. just like what happened now.. "

<p>"I know the reason you changed the note was to cover my left hand weakness.... Starting then I began to notice you.. This kind person.. you had always been very kind to me.."

<p>"Why... what's wrong with me? Why is it Katagirisan.. ? Why it isn't me... Ne senpai.. why?... "
"....."
"I'm not a sister.... I'm not a sister...."
"I... more than Katagiri.. I like you more than Katagiri!!"

"I wish I have never joined Irodori!!"
She ran home.. leaving you alone at the playground.. thinking of what have just happened.. why you haven't noticed that so far.. about her feelings.. but it has happened, and you can't change it....
