The chime rings at the end of the class. As soon as I hear that, I begin my journey home. To leave as soon as the home room is finished.

"Oshima, I appreciate you taking my class seriously. Can't you at least wait till the house is finished?

When my teacher told me to raise my face, the teacher who knew my sister's situation rather than mine was smiling bitterly. I know I'm not serious, so I say it with a smile.

"I don't think so. If you're one second late, you'll lose one second of visiting time. So, Doctor, let's get this over with. Come on, come on!

"Absolutely...."

Though astonished, the teacher briefly conveyed the contact details. That's right, Doctor!

Immediately the home room is finished and you take your seats. Then a voice was heard from the next seat. You're a familiar little girl.

"The future. We're all going to Karaoke after this, but the future won't come, right?

You know what I'm talking about.

"Yes, of course. Really, your sister is at the center. It's so cute. That girl."

"My sister is the cutest in the world!

"Shut up, Cisco. Go quickly."

I was angry. He waves his hand to everybody and leaves the classroom, depressed. Everyone in this class is kind and looks back with a smile.

Leaving school, you go to a university hospital next to a station.

I am Oshima Future. I just got into high school this year, and high school is above and below. My junior high school teacher told me that I could look up, but I didn't want to go to a school where my studies would be delayed if I didn't get desperate.

I have an older sister. If you go to school, you'll be in second grade. Last year she suddenly became a family sister. He is the child of his father's remarriage partner.

My father divorced himself five years ago in various ways. Well, I don't know what to say... My mother left. I don't know why. My father didn't tell me either.

I grew up with a man for a while, but it looks like I had a good encounter at the hospital where I work, and I married him last year. That person, my current mother had a child. A girl with a slightly troublesome illness.

So, well, there were many things about my father's remarriage. The mother, who is nothing else, objected that it was better to stop. The reason is simple, because you have a sick child, and you're going to have a hard time.

My father told me many times that it was okay, but it seemed that my father's children, that is, I would not be convinced, so I decided to meet his mother.

Dining at a nice restaurant. So, listen to the child, listen to the feelings of the two of you, and then tell him that you want to see the child.

I went to the hospital the next day and received a visit.

I fell in love at first sight.

No, wait. That's not what I meant. I don't have such a hobby.

However, she was so cute and so eager to protect herself.

When she first saw me, she leaned her neck strangely, who was it? Ask him.

In the meantime, she was cute, so she hugged her and said to her father and mother who were going to be stunned. Become this girl's sister. Needless to say, they were both stunned... Oh, my God.

After that, the conversation progressed very rapidly, and the following month, I officially became a family, and I had an old, bloodless sister.

If I were a boy, I might have started a love comedy. Unfortunately, I am of the same sex and neither my sister nor I have such a hobby.

But I love this sister, Karen. He's publicly saying he's drowning. She's a cute, precious sister.

That's not why I'm here! Sorry to bother you again today!

Enter the hospital, go through the visitation procedure, and go to the tenth floor. The hospital room for my sister is a little special, but it's not a sterile room or anything like that. So I knocked on the door in my uniform.

Knock, open the door and go inside. A small room. A truly small room with space for lockers and luggage. Putting aside the unwanted items and turning off the lights in this small room, the key to the back door came off even further. If we don't darken this place, we can't go any further.

Opening the back door leads you to a dark, but expansive, room. There are no windows. The lights on the ceiling are also off, and only the small pale light bulbs in the corner of the room are the only light source.

"Ron-chan, I'm here!

Say hello to your sister in bed, Ron. But I haven't heard back.

"Mm...."

Around that time, when I looked inside the bed, a girl with white hair fell asleep... ah, this looks like she fell asleep. I'm wearing a laugh.

Hmm. Then there's one thing to do.

"Oh, is Ron asleep? Then go home."

"Wow! No, no, no!

Len-chan is in a hurry and sticks to my arm. Cute.

"Don't go!

"Yes, yes. It's okay. It's okay. It's okay. I'm right here."

"Mmm...."

"But Roon-chan, who tried to mess with you, is bad."

"Nh... I'm sorry."

"I forgive you."

Remove the chocolate from the bag whilst keeping Len naked. If I gave it to you, Len-chan's face would shine.

"Thank you, Onee-chan!

"No"

Break the packaging happily and start eating. A happy face.

When I was looking at the smell and the state, Len looked right at me. Len-chan immediately breaks the chocolate into small pieces and serves it to me.

Hmm?

"For oneechan."

"Ahahah. Thank you."

If I refuse, it will be stubborn, so I will thank you for it. When I ate it, Len-chan was happy too.

My sister is too cute. Angel. No, she's already a goddess. Let's take a look.

"Hey, what are you doing...?

I'm praying.

"Why?"

"Renchan is a goddess to me!

"Hey, it's disgusting."

"Ugh...."

That curse comes to my heart, Lotus...

Renchan is extremely sensitive to light. It seems that even fluorescent lamps and other lights cause inflammation, and if you go under the sun, it will quickly hurt and cry. I only asked my mother because I had already stopped coming out of this room when I met Ron.

Originally, it seems that light sensitivity reacts to sunlight. But Roon-chan seems to react to any kind of light, and without keeping the room always dark, daily life can't be much easier.

The cause is unknown. It seems that I have done a lot of blood tests and tests with a small and difficult name, but it seems that I didn't know the cause at all. It was the only strange disease in Japan and was featured on TV.

As far as I'm concerned, I don't like it as a sight to see, but I don't seem to care about it personally. No, maybe you just don't know what that means, not that you don't care. I hardly even watch TV.

My father seems to have been worried about the interview, but he gave me permission to solicit donations for medical treatment and so on. Since then, medical expenses, including hospitalization expenses, have been covered by donations. Renchan was worried about money, so I'm relieved about that.

I've been taking a rest test to make sure it's not a burden on Renchan, but I still don't even know the cause rather than the treatment. It's going to be a long time.
