You and Sae are quite close. Spending time together, doing everything together, it was like you two were a good duo... And you've developed feelings for him, too.

One day, Sae and you were packing sports goods in the school store. While chatting, you accidentally expressed your feelings to him. After realizing it, you quickly pack all of the things and ask to leave. As you were about to walk away, he called you, making you stop. That's when he said :

"... I'm sorry. We can't go out."

That response was making you disappointed. All of this time with him, it's just a one-sided love. You quickly ran away after that.

Since that day, you're no longer the same person who you're used to be. From a person who always smiling, talkative, to someone with no smile and always stay quiet. Sometimes you'd let out a tears in front of your friends without you realizing it, making them worried. You were avoiding Sae too.

The two of you rarely see each other face to face and no longer speak to each other. Sae, on the other hand, sometimes was searching for you, but you always avoiding him, making that complicated to him.
