"I'm home, you brats."

The sibling's mother just arrived home after a hectic day at work and Rin already can't wait and cling onto her mother's arm.

"Ka-chan, just now a weird girl came demanding for nii-chan. Do you know what was going on?"

For the slightest moment, their mother flinched and this caused Tsubaki to even put down his book and stare at her.

"Demanding for Tsubaki? Wh...Why?"

"She said something about me snatching him away from her and a man said something about coming on a later date? It was very what the fuck moment basically."

"Rin, dearie, let ka-chan have her rest or at least shower first. She just came back from work."

"Okayyyy. It doesn't matter anyways, she probably got the wrong person."

"I...I'll be going to shower first."

Rin thought nothing of it yet Tsubaki knew that their mother was acting weird. It was something but Tsubaki couldn't put his finger to it. Maybe it was work he thought. He thought

In the showers, unknowingly to anyone, their mother was afraid. Her heart beat so fast that it felt as though it might come out from her throat. She turned on the showers and stood there rooted. She couldn't figure out what she was going to do. Even her thoughts was unorganised, she was going to have a panic attack. She started to cry. Crying from fear, ignorance and sadness and by this time, it was impossible to tell which was the water from the showers or her tears. 

They must have found out. Tsubaki will hate me. Rin will too. What am I suppose to do?

"Ne, nii chan, ka chan ate really little today."

"Ya, maybe she is too tired from her work."

"Of course, maybe her change of shift affected her too. Anyways, help me with homeworkkkk."

"Are you sure you want help or someone to do it for you?"

"If that was the case I would have went to Kaito."

"Alright, lets go to our room."

Although Tsubaki seems to be fine he was still troubled by the fact that such weird incident has happened and how their mother seems to be so out of it. Rin on the other hand felt something was amiss but since she couldn't do anything, she decided to let time do the job for her. Time always heals everything. Right now, her homework was more important than anything.

Next day the pair went to school as usual with Kaito. In front of the gate stood a man that Rin spatted at yesterday. Rin decided that she had to deal with this confused poor yakuza or whatever he was. Rin asked Kaito to drag Tsubaki away first and Tsubaki complied unwillingly.

Rin took a deep breathe and went up to the man.

"What's your deal with my brother?"

The man then looked up at her from his phone. He flashed a kind smile. One that Rin knew was up to no good.

"Isn't Asahina Tsubaki always with you? Where is he? I need to meet him."

"Why do you want to meet him?"

"Well, young lady, it seems like your mother has never told you."

"Told me what?"

"You and your brother are in no way related." The man made the inverted commas sign when saying "brother". 

Rin was stunned. What is this man saying? Her and her brother are in no way related? He must be crazy. Rin was firm in her belief that Tsubaki was most definitely her brother because after all, he was the first person she recognise when she started to be able to recognise faces. Rin snorted and said,

"You must be high. Ask around the neighbourhood before saying stupid shit like that."

"Take a DNA test. This is a lock of hair from the girl you saw yesterday. Tell me the answer when you realise the truth."

The man gave Rin a small plastic bag zip bag with a lock of hair and his name card on top of it and left.  Rin held on the two item and froze for a solid minute. When she came to her senses, she walked towards the dustbin and wanted to throw the two item away but she stopped. She pulled her hand out of the dustbin and for some reason stuffed the items in her bag.

She was unsure of how to feel but she definitely didn't like it.

"Rin chan? Are you ok?"

"Ya..."

Tsubaki could hear that hint of unsureness in Rin's voice and he wants to know why.
