L gave Zelo a death glare. He totally mad and Zelo just yawning and totally ignored him, but then Zelo held out a hand to L, “Hoahmmm.... Fine~~ L L L L L L~ Annyeong X.L.~ My name is Michael AnZelo, but you can call me Zelo. And... I am your guardian angel~”

L gritted his teeth, “My name is L. NOT X.L!”, Zelo just blinking his eyes. “Okay, so you said you're my guardian angel? How can I believe you? Do you have proofs?”, L ignoring Zelo's hand.

Zelo pull out something from his pocket that looks like a photo.

He held it in front of L's face and said, “This is you, right, LG?”

It's a childhood photo of L in his middle school, with his big-high-wide-funny-hairstyle.

L's eyes grew big just like a tomato and he yelled, “DAMN! YOU! Where did you got this picture?! I really hate this one. Don't you dare showing to anyone else or I'll cut you into pieces! You hear that?! And I'll tell you for the last time, MY NAME IS L NOT LG!!”, Zelo winced to his loud voice, and made a face.

“It's Zelo's secret, LCD. My leader told me to be your guardian for 6 months”, Zelo smiled.

“For God's sake I'm not LCD.. My name is L”, L sent his death glare to Zelo, “Okay now, you're really my guardian angel? But you are only a kid.. And your style...”, L looked Zelo from head to toe and he started laughing.

“Why are you laughing?”, Zelo asked.

“You don't look like an angel at all.. In fact, you look like more an idol. You know... An angel should at least...”

“What? Use white-long-dress and have wings?”, Zelo cut L and raised one of his eyebrow.

“Well you can say that.. But you are way too different with the angel I have met before..”, L continued.

“Zelo just follow the trend. Anyway, this is not my real face. My leader said that I can get my real face back if I can move to the next level... Zelo believe that Zelo's real face is cuter than this one.. So Zelo accept this challenge..”, Zelo said calmly.

“Wow... Dae-bak. So you can get your real face.. Hmm.. But wait, what are you before? How could you lose your real face?”, L confused.

“The leader said that Zelo once a human too. But Zelo has already dead. Zelo didn't remember anything about that. They erase Zelo's memories as a human. Zelo only can get it when Zelo become a scheduler..”, Zelo smiling like a innocent kid.

“Scheduler?”, L raised one eyebrow.

“Yes, the Angel that you met before, the one who brought you back to life, is a scheduler..”, Zelo answered.

“But he or she doesn't have a face, I couldn't see it since it's too bright..”, L confessed.

“Well, most schedulers take form as a light, not everyone could see their real face when they are still human, but a scheduler can decide to show their face or not..", Zelo explained.

“What? So.. What's the different between you and me? Why don't you try get your second life?”, L asked Zelo.

“Because Zelo is different with you. Zelo has been died in a different way with L. You are a 'half-spirit'. People who can be a half spirit like you is they who got the unfair death, died in an unfair way. Zelo still don’t understand why  Zelo became an angel though. Maybe they will tell me after I can be a scheduler..”, Zelo shrugged his shoulder.

“What’s that? It’s too complicated.. Anyway, why they chose you to help me? How can you raise your level?”, L looked more confused.

“If Zelo success in helping L finished your missions, I can change my level. Meaning, if you success get your second life, I will also be success become a 'scheduler'..”, Zelo answered.

L gave him a quizzical look, he got more confused than before.

Zelo got the sign and cleared his throat, he explained, “In short, I can tell you that there are five levels of Angel. The highest level is called ‘HEAVEN ANGEL’, we usually call them with holy spirit, the second level is ‘SOLDIER ANGEL’, they are angels who do the war with the devils. The middle level is called ‘SCHEDULER ANGEL’. R
