Mystic Messenger Headcanons, OneShots and FanFics Part 1

RFA + V and Saeran who read Mc's diary she already has since childhood

Jumin

When he came home he found all his books on the floor and you almost crying.
,,Mc?! What happened? Did someone hurt you? Where are the-"
,,I can't find the book...!" you mumbled.
While you went in the kitchen to prepare his meal he searched the book for you and found something even better-your diary.
,,That's something common people do, huh?" he read it.
But he was really sad to read only bad things.
Like, when you had a bad mark or when something happened.
But the last 11 pages made his heart beat quicker.
You wrote how you entered the RFA. How happy you were and...how much you loved this one man.
On the last page you drew a big heart and wrote his name in there.
His cheeks got hot and red...
,,Jumin did you-MY DIARY! Jumin!" you were so embarrassed.
But when you saw his face...you couldn't be angry at him.
,,Mc, I love you so much..." he pressed his lips on yours.
The book you were searching for was already forgotten.....

Zen

He always wondered what you were writing in this thick book...
One day you went shopping with Jaehee and he decided to look into it.
He regretted it immediately when he noticed that this book was a diary in reality.
But he couldn't stop reading.
,,Since her childhood, huh?"
The thing that shocked him was reading about your first love.
He was so jealous that he threw it away, breaking it.
,,Oh...fuck."
,,Zenny I'm home!" you called him and noticed your diary.
He looked at you.
,,I'm sorry...please don't be angry...I read about your first love and....sorry."
There was an odd atmosphere but you laughed and kissed him.
,,Did you read the last few pages?" you asked him, still laughing.
He didn't.
But now you were reading it together.
He blushed hard while he read the things your wrote about him....
,,If you dare to read my diary again I will stop unleashing the beast." you whispered.
You were angry after all.

Yoosung

He knew that you had a diary.
His sister also had one and he knew-don't dare to read a woman's diary.
But you left it open and he couldn't stop himself....
There were only happy things in there.
He was happy to read how cheerful you were.
,,I'm afraid. What if he gets hurt? I love Yoosung."
He was sad to read that since he came into your life you were haunted by fears and thoughts.
Tears came and you noticed them.
,,Yoosung! What happened?" you asked your husband and noticed the page.
,,Am I holding you back? Are you unhappy with me? Is it painful?" he wanted to know.
,,Yes. It's painful. I'm afraid. If you would leave me...I think I would break apart...in the past I had nothing to care about but now....I love you so much." you comforted him.
,,I'm sorry."
,,Don't worry. I will give you a proper payback."
,,Ah thank you-NO MC!"

Jaehee

She always wondered why you had a diary.
You took it and let her read it.
,,You know, there are some things I can't tell anyone, for example when my classmates bullied me. And so I use my diary. The pain gets better." you explained.
She was sorry for you but still grateful to you.
She was happy to read it and to read the kind things you wrote about her.
,,Thank you very much for letting me take part in your past."

Saeyoung

He played a prank on you and bought the same diary you had and hide yours.
Afterwards he burned the new one.
He just didn't think you would react like that, crying and screaming at him.
He was shocked when you screamed something about a present from your dead mom.
,,No no no Mc, this is a prank look! Yours is here..." he tried to calm you but it was impossible.
You were so tired after crying that much....you just slept.
He used the time to read your diary.
You also wrote something about him.,,Mc...I'm sorry for playing that prank on you..." he whispered while you woke up.
,,Bad ass you read it..."
,,I'm sorry."
,,It's okay....hug me, please?"

Saeran

He wasn't really interested in your diary.
It was yours, he had no right to read it.
But he was really unsure why people had a diary.
What were you writing?
He isn't interested, don't lie.
He wanted to read it but it was locked up.
Scary, what were you hiding?!
It was for your own good lie
He had to read it.
But he has to be honest-it was really boring.But he was exciting to read so much about himself....
,,You're dead." you told him as you caught him.
,,I-Sorry....oh?" he looked at you, shocked.
,,I'll give you ten seconds to run and then I will kill you..." you smiled at him.
He used the chance you gave him and escaped.

Jihyun

He was surprised when he saw a diary in your shelf.
His fingers tickled, he wanted to read it so bad...but he couldn't.
But he did.
He chuckled at your sweet hand writing.
Your thoughts and some of your secrets.
,,Jihyun, what are you doing??" you found him reading your diary.
,,Nothing dear. I'm sorry..." he excused himself.
And hugged you.
You were happy that he didn't read the last page.
And he was happy that you didn't notice his blushed face because he read the last page....
