<h5 class="has-text-align-center">Even confession feels like an NTR</h5>\n The first time Rin expressed her affection for me was when I was in the second grade of elementary school. When I was playing with Rin at the park, she said to me out of the blue, 
 “I like you, Riku-chan, and I want to spend all my life with you.” 
 Normally, I would be happy to hear a girl confess her love for me, but at that time, to my own surprise, I felt surprisingly bad.
 
 
 
 I truly felt that childhood friends are really scary creatures. Like wine that ages for years, childhood friends take a long time to brainwash their partners. 
 They make you think that they are the only one who is thinking of you, and then, as soon as you become sexually mature, they plunge you into the abyss.
Childhood friends are truly terrifying.
 
 
 
 I made my childhood friend cry by telling Rin in a trembling voice, “Don’t ever say that again.
 
 
 
 My time with Rin was full of things that could poison me in the future if I allowed myself to let my heart go.
At a local summer festival, Rin and I wore the same happi coats, pulled the same floats, and watched the fireworks that lit up the summer night sky. 
  Before the excursion, we went shopping together for snacks, and after the excursion, we were both covered in mud. On nights when meteor showers were visible, Rin would sneak me out of the house and we would gaze longingly at the sky, even though we could hardly see any shooting stars. Rin always seemed to be enjoying herself, but I felt complicated as if I was repeating the time with Yui again.
 
 
 I couldn’t believe I was going to throw myself at her. It wasn’t just my love for Yui that had made me feel the urge to throw myself into the abyss that time, it was also the fact that my heart was broken.
 It was the time I spent with Yui that made me do it. The intense time I spent with my childhood friend became a poison that killed my heart.
 
 
 
 I cannot repeat the same mistake. I told Rin many times that I would never see her again, and I made her cry. Each time, Rin would say,
  “I belong only to Riku-chan. I will be with you for the rest of my life.”
  In the end, I lost my patience and ended up spending time with Rin, but I never trusted my childhood friend.
 
 
 
 
 
 Thus, fifteen years had passed since my reincarnation, and I was a high school student again. Come to think of it, it’s a wonder I hadn’t thought of it before, but I suddenly wanted to know what my acquaintances from my previous life were doing now. It has only been sixteen years since my death, so most of my acquaintances are probably still alive and well.
 
 
 
 I was able to obtain a lot of information through social networking sites. The male friend I was closest to had become a father with a child and was working for a well-known company.
  My friend who was the most handsome guy in high school has grown fat and is now constantly posting on social networking sites about his idols who are not even old enough to be his friends. The future is uncertain, really.
 
 
 
 And with some hesitation, I decided to find out more about Yui Shiraishi, my childhood friend in previous life and Takatsuki, the guy who slept with my childhood friend.\n
