Modification

Ao and Kosaki are in the living room of Onodera's residence sitting next to each other and whispering.

"Why did you say you were my boyfriend?"

"Is it wrong?"

"N—Yes!"

After this short dialogue, a voice of a young woman can be heard behind them.

"I can't believe…"

Haru said as she tighten the grip of her hand while closing her eyes. She opens it immediately to look at them again.

"… I disagree about your relationship!"

Haru pointed her index to Ao with an expression telling him not to steal her sister from her.

"Why did you disagree? Don't you want your sister to be happy?"

Hearing his words, Kosaki suddenly blushes but she immediately shakes her head because this is not the time to do that. Her sister really believes that Ao is her boyfriend.

It's not that she doesn't want to but she's still confused about her feelings for Raku and Ao.

She has known Raku for a long time since they were in middle school while in Ao's case they just met again and only talked to her for a short time today.

But even so, she doesn't know why she feels more strongly affection for Ao than for Raku. Maybe she doesn't really like Raku from the start and her heart is used to beating for Raku because she just admires his kindness.

But she can't say she likes Ao, because they only met and talked today. They don't have a bond yet so she is confused as to which one of the two of her heart belong?

But while Kosaki was thinking, Ao and Haru continued to argue. However, she snaps when Ao suddenly holds her hands again.

"Wha… Get off your hands to onee-chan!"

Haru suddenly was about to tackle him but Ao nulls her hands and hug her.

'I have no more patience. I want them to be mine now.'

When Ao thought of this, he immediately controlled their wills and changed their character a little.

He made Kosaki's feelings for him more important than Raku's and he helped give her brain a way to remember what happened to them 10 years ago.

He also did this to Haru but there was something different about her character. When he does something she doesn't want or isn't ready for, she will fall for him even more.

At first, he thought to enjoy this small event but his patience started to get shorter because even though their feelings change quickly, they can't make a decision right away.

He then remembered that in the original series they were like this so Haru surrendered her feelings for Raku for the sake of her sister and Kosaki was rejected because she didn't dare to say her feelings for Raku in the early of the series.

Instead of that happening again, he thought that he should get them both early. At least, they won't be hurt but they will feel weird about their relationship with him because they belong to one person. So even for a moment, he changed their character as a decisive person and their feelings for him, excluding the truth about they just know and met him today.

After he did that, he immediately got a headache. He was given a lot of stress when he used his powers on the two of them because of the barrier that blocked the brains of both of them that was created by the plot to make it a shield to his powers.

This plot really gets in his way but it didn't stop him from changing the two of them. While the two of them were in the process of the change, they looked up and were silent.

When Ao finished his modification, they woke up and immediately felt different about the man in front of them.
