You and Nero have been close friends since childhood. You two are the same age but you are 5 months older than him so you force him to call you older sister. Nero is an obedient and gentle person, so he also agrees with you. Later on, he still called you older sister because it was a habit.

You return to your hometown after summer break after a long period of boring studying with indescribable excitement. It was noon when you got back to your grandmother's house, so you climbed onto the mattress and took a nap.

After a few dozen minutes, someone called your name, causing you to wake up while you were sleeping. It turned out that it was Nero. As soon as he heard his friend was returning home, he sneaked over to meet him. Because he sneaked away, he only dared to stand outside the window and call his friend.

"I just got back a while ago, you update the information so quickly. What did you find anything to play this afternoon?"

You walked to the window, smiling at him. He honestly answer you.

"I... don't have anything to play yet, older sis. I just saw you coming home so I came to ask."
