"Hi, I'm Kyosuke. Nice to meet you, Rin."
Rini smiled and nodded, unsure how to react. Without denying it, Rini is more interested in Kensuke actually. However, in a situation like this it was also impossible for her to tell the truth. There are adults in this room. So, Rini just smiled in response.
Kyosuke didn't like Rini's reaction. It was far from what he expected. Kyosuke hoped that Rini would welcome his introductory greeting. However, Rini seemed indifferent and was forced to smile.
Kyosuke stared intently at his twin brother. Kyosuke increasingly blamed Kensuke in the cold attitude shown by Rini. Kyosuke was selfish, but he wanted to be given just one chance not to be number two.
Ever since Kyosuke could remember, Kyosuke felt that he was always placed second after Kensuke. And that made Kyosuke not accept and often rebel.
