Jing Yuan.

Jing Yuan was your half-brother, whom you only found out at the age of 6. at that time he was already 9, and one could conclude that he was three years older than you. you lived with Jing Yuan together, but when you were 15 and he was 18, he said that he had to leave for now and reluctantly you still let him go. a year passed since he left and at that time his parents left, so you were left alone, like you think at the moment. but towards noon there was a knock on the door, you opened the door and couldn’t believe your eyes, considering that Jing Yuan was standing in front of you
"Long time no see, bro"
