After some time passed and Kiriha had calmed down a little. She slightly separated from Koutarou and looked up at him.
“...Hey, Onii-chan.”
Kiriha whispered and smile.
“Hm?”
“I'm actually a little troubled.”
As Kiriha said that, she put the necklace she had been holding in her hand around Koutarou's neck. To her, that was its rightful place.
Next, after she had shaken her card a few times and showed it to Koutarou she held it against her chest with both arms. That was also its rightful place.
“What's troubling you?”
Kiriha continued crying as she spoke and tears ran down her cheek and fell off her chin, wetting her hands and Koutarou's necklace. Noticing that, Koutarou reached his hand out towards her cheek and wiped her tears away. That made Kiriha happy, and she smiled, and shed one final tear.
“Kiriha and Kii are arguing inside of me. Kiriha wants to trouble you more, while Kii wants to stay like this.”
“Ah, then you don't need to argue.”
Koutarou let out a small sigh and dropped his shoulders.
“Why?”
Kiriha tilted her head like Kii would. She should have had the same face as always, but right now she looked like a young girl.
“...The glances from people around us are stabbing into me. They must think that I'm making you cry.”
By having Kiriha rely on him like Kii, Koutarou was being troubled. In the end, the results were the same, regardless if it was Kiriha or Kii.
“You ARE making me cry, geez...”
After giving Koutarou a very Kiriha-esque mischievous smile, she hugged him like Kii would. The two girls melded into one and threw their feelings at Koutarou.
“Then let's go.”
Koutarou smiled bitterly as he whispered to Kiriha. Strangely enough, he remained calm even as Kiriha was hugging him. As a results of his feelings for Kiriha and Kii merging, he believed this was normal. He was feeling something similar to the way he was feeling towards Sanae.
“Where to?”
Kiriha closed her eyes and whispered back to Koutarou as she continued to hug him.
“We're getting on the roller coaster, obviously. We stand out here...”
The surrounding people staring at them made Koutarou more uneasy than having Kiriha hug him.
“Trying to get a girl in the mood by taking her on a ride... don't you think you're being a little too simple?”
Kiriha looked up and smiled. She then let go off Koutarou and held his hand. Though she had criticized it as being simple, she seemed very into it. That was of course only obvious, since she had waited for this moment for over ten years.
“I don't. I told you before, didn't I? I'm actually very interested in roller coasters... I just want to ride it myself.”
Koutarou began walking. Kiriha naturally accompanied him and she gently rested her cheek on his shoulder. The two passed through the entrance to the roller coaster as if they were lovers.
“By the way, Onii-chan, who were those words for? Was it Kiriha, or was it Kii?”
“I forgot. Does it even matter?”
“Fufufu. I'll just leave it at that. Koutarou and Onii-chan are both shy.”
“Shut it.”
The winter cold had properly settled in on this February day. The sun was setting and the evening began growing colder. And in the amusement colored orange by the sunlight, the roller coaster zoomed by at full speed.
Nothing special had happened on this day. A boy with an antique necklace and a girl with an old card had just gotten a ride on a roller coaster together.
It was a very normal event on a holiday.
However, it was also an event that dramatically changed the two's relationship.
