4 years ago before getting isekai'd:

I was living in a big house with Hikaru, I didn't know where my parents were at that time or what happened to them, I don't know to this day but what I can assume happen is they left me when I was young, Hikaru's family became my foster family since I was little. Hikaru and I didn't grow up seeing each other as siblings, tho.

"Hey, Hana. How are you?"- I am now at school, drifting off in my thoughts. There is this girl at the front desk, Kirara, I get along with her pretty well, you can say we are best friends.

"I am ok. I just thought about something"- I looked down and made it look like I was looking through a book or something similar.

"You sure, you don't seem like it"- Well, she can see through me huh?

The main thing that is on my mind is my real parents, what have they done? Why did they leave me here, where are they now? I can't keep relying on Hikaru's parents.

"You are right, there are things that are on my mind. But I don't want to talk about them right now. The class will start soon, maybe in one of the breaks if you are up for it?"- I looked at Kirara, and we both stared at each other for a while.

"Sure"- She said turning away from my desk.

I looked around the class again before the teacher could come, I could see Hikaru, he was staying in a corner of the classroom, he is laughing all by himself staring at a wall.

Things with Hikaru are special, to say the least. He sees shadows or voices when no one is talking, and he often speaks in ineligible sentences that no one will understand, but he is trying his best at school every day of the week.

The class wasn't fun, like most classes are, I mostly stared at the teacher and noted down boring information, well most of that information is useful for me down the road but the way it is being told is very boring.

The class has passed, me and Kirara had gone to the rooftop one of the most infamous places in our school.

Every year on this rooftop a student of this school commits suicide, and the principal does nothing about it, it seems like she doesn't care, she managed to cover up a lot of the things that happen at this school, I don't know for how long will she manage to hide all of them, she put a "fence" on it but that fence isn't even properly placed since students can get over the fence or under the fence with ease.

"So, what is it that is bothering you Hana?"- Me and Kirara gone to the furthest part of the rooftop to have a conversation, away from everyone else that is there.

"Well, it's about my biological parents. You don't know how I live or what family takes care of me right now do you?"

"No, I don't know"- Kirara leaned in closer to me.

"I live with Hikaru's family, they are my foster family, they took care of me for a long time, since I was little"- Kirara had a shocked expression.

"So, you and Hikaru grew up together. I never thought that weirdo had a sister like you"- Why does she call Hikru a weirdo?

"Why do you call Hikaru a weirdo? I am curious, most people seem to think that something is wrong with him"- I looked at Kirara with a serious expression.

"Well, I guess since you lived with him everything that he does may seem normal to you but to us, it's very weird, he hears voices, and he sees things that aren't there. It's very odd and not normal to be this way, Hana. I am sorry to break it to you but Hikaru isn't normal, he is very odd"- Kirara whispered in my ear.

"I know already that those things aren't normal, but that doesn't make him unusual or anything. These problems can be treated from what I know. I don't like how people treat Hikaru"- I whispered back to Kirara.

"Well, I can't comprehend the way you think, but anything goes I guess. Now back to the real topic, your parents, do you not know anything about them?"- I got closer to Kirara as more people came to the same part of the roof.

"Well, from what I know they have abandoned me and I don't know where they are, I don't have the slightest idea of what happened to them. Hikaru's parents always told me that they don't know what happened to them, that they just vanished into thin air, that's what they said"- I looked up at the sky, I don't want to make eye contact with anyone here, I don't want any unwanted attention.

"Well, that does sound like they abandoned you. I don't know why would they do that, or maybe they were kidnapped or died during a horrible event, that may also be true"

The bell rang, me and Kirara gone back to class.

After class is done:

I am walking home with Hikaru, he's looking left and right, and he is paranoid about being followed home.

"It's ok Hikaru, no one is following you, I promise I will keep watch. Please rest easy"- I don't like seeing him like this at all, this illness that he has and doctors wouldn't even tell him what he has, if he is told what he has we can at least rest easy knowing his condition and how to treat it.

"If you say so. I am still going to look from time to time just to make sure"- Hikaru walked a little closer to me.

When he is at home Hikaru always wants to be isolated from society, I barely can do anything about it. He is pretty neutral about me entering his room.

"Sure, but don't bother yourself too much"- I am the one bothering myself with 2 things at once now, where my parents are and Hikaru's illness that I have to deal with.

We reached home, we changed and we went straight to learning. Hikaru paused for a bit and looked at me, he put his right hand on my left shoulder.

"I am sorry Hana, I know you have to deal with a lot. I am aware I am bothering you"- Huh, how did he?

"Well, you aren't bothering me. It's just too much for me to deal with right now"- I didn't notice it but began crying.

"I know, about your parents as well, I have no idea what happened to them either. But I am sorry for any problems I have personally caused to you"- I turned away from Hikaru so he couldn't see me cry, I need a break from all of this.

"If you want to be alone I will leave you to it. I will go and learn in my room"

"No, I want you to stay here"

I was silently crying, it was a slower cry, I want to discharge as much emotion as possible. I leaned on Hikaru's shoulder and I continued to cry for a while until I got sleepy and fell asleep.

Hikaru's POV, current day in the other world:

"Sia, why did you have to remind me of this?"

!Note that your emotional intelligence is higher now because you no longer suffer from schizophrenia, also your mental functions are normal right now because you were reincarnated here.!

"Yes, but still that doesn't answer my question"

!I gave you that memory to make you feel better about yourself!

Still doesn't help much, anyway, tomorrow is a new day, and we will need to gather everything we can and make a move on the local lord.
