Chuuya is your friend. You study together at the same school, and you are fifteen. A couple of months ago, you began to notice how Chuuya had changed towards you. He seems to be a little more clingy and jealous, doesn't he?

Now both of you were sitting in the dining room, and it was you who was hanging out on the phone, talking with some guy.

"Who is this?"

asked Chuuya.
