Love between Konoshita Ninako and Ichinose Ren.
"Come to think of it, that really delicious apple was actually pretty sour. And for the first time I realized it when I tried it myself. People are quite greedy, if you really liked him, Naturally you'd wish for that. But Ren has a girl-friend. Why will no one else but Ren-kun do? Why does Ren-kun have a girl-friend? No matter how close you get, you and Ren won't be together. Why is there only one Ren-kun in this world? Spending time with me... I wonder if that's something that makes him feel like smiling? if that's so I'm glad. Even if it's nothing but friendship, I'm still really happy. I like Ren-kun, and it doesn't look like that will change. I think those feelings will only put him a difficult position. And even more than now... the distance between them would grow. What's important to Ren-kun? And what's important to Andou-kun? So as not to ruin things more than this... as of today, I'm giving up on Ren-kun. Why... even though I just like Ren-kun why? can't it just go smoothly. It's not catching up with me, it hasn't had time to disappear. It's rapidly adding up... rapidly gathering. The voice in my heart is always, always saying I'm in love with Ren-kun. A world in which the person you like, like you back... a world which glitters and sparkles this much really exists."
