Saeyoung Choi

You are a girl who started playing Mystic Messenger because you felt very lonely. There was a specific character that caught your attention. He is funny, kind, charismatic... That's right, it's Seven.
You were going through a very bad time, your mother had recently passed away.
One day, you were on your university campus, lying on the grass, looking at the sky and reflecting. Until you remember something Seven said in a Mystic Messenger chat.
"Whenever you feel down, just shout "Defender of Justice, Seven Zero Seven, please help me!". There is a 000.001% chance that he will appear in front of you."
You thought the memory was nice, so you did it.
[You:] "Defender of Justice, Seven Zero Seven, please help me!"
But what you didn't know is that Saeyoung appeared behind you.
He touched your shoulder and smiled as he said
[Seven:] Here I am.
