warning: incest (not really but ok)
———
Amane is now officially adopted to the Yashiro family.
Ever since that day, Amane and Nene has been close since the girl is always been so lonely without a sibling.
Amane's parents (including Tsukasa) died in a car crash when he was only 4 years old and Nene was 3 years old.
Now Amane is 17 and Nene is 16.
Amane had a...little bit of crush and obsession towards his 'sister' since the day they met.
But Nene only saw him like a big brother that he is always there for her.
That, of course, made Amane feel very angry. But he didn't let that go through him.
Amane has always been....a bit aggressive they say.
But Nene didn't believe that, she thought that it was just his childhood trauma that caused that.
And that was the reason why Amane liked Nene.
She was like a drug, that Amane got addicted to.
Well, since Amane is almost at college— their parents thought that it might be a good idea to let them stay at his own, with Nene of course.
And Amane was excited— Nene with him in a house, with no one to bother them.
Alone together.
Although the neighborhood they were in were not very a crowded area,
I mean, Amane is also very happy about that.
...
It was the day when they were moving in.
"Amane-kun, Amane-kun! The house is really pretty isn't it?" Amane can't help but chuckle at Nene's childishness.
He looked at the house.
She's not lying, the house is really great for two people to live in, it was a 2-story house.
With a kitchen on the right side, living room on the left. And a dining area just right in the corner of the kitchen.
{im not really good at describing the details, sry just bear with me}
The stairs were just right in front of the door, and underneath the stairs was more like a small storage room.
And Amane's room and Nene's were just across to each other.
Amane's to the right and Nene to the left.
"Hey Nene! You know how to cook right?" Amane shouted,
"Yeah! And don't even think about me making us dinner!" Amane chuckled again. He place the bags down— and walk into the kitchen.
Time skip
It has been 3 months since they move and Nene had been noticing that Amane is very...touchy.
Whenever Nene would be in the kitchen cooking something— Amane would sneak up behind her and hug her from behind. And that, made her feel a bit uncomfortable.
And there's this one time where they're in the living room doing some sibling-bonding-time, she could feel his hands on her left thigh.
Maybe he doesn't know what siblings work? No, that's not the point.
Amane wasn't like that before, so it's very very weird for him to do that to his own sibling.
And whenever they would go to school— Amane always stops by and look to Nene in case she got missing or got harassed by disgusting men.
