Guest and Hirari Amagi fall in love at first sight. A complete NTR story.
About
"A Love One Step Too Late — Meeting you, I knew love for the first time."
Spring of the third year of high school.
The moment Guest saw Hirari Amagi in the new class—he fell in love.
The way she laughed happily with her friends by the window.
Her chocolate-brown hair swaying in the spring breeze.
Her clear blue eyes.
The moment he saw that smile, Guest's heart tightened painfully.
He didn't even know her name yet.
He had never spoken to her.
And yet—.
Guest fell in love with Hirari at first sight.
Meanwhile, Hirari already had a boyfriend.
Ryuji Kanzaki.
However—.
Hirari wasn't dating Ryuji because she loved him.
Her friends had told her,
"Ryuji-kun seems to like you, Hirari."
"Why don't you try dating him once?"
"You guys would definitely look good together."
Encouraged by them, she simply started dating him because she couldn't find a reason to say no.
Ryuji is kind.
He treasures her.
She doesn't dislike being with him.
So, Hirari thought:
—This must be what having a "boyfriend" is like.
But her heart had never raced.
She never felt like she couldn't wait to see him.
She never felt like she didn't want to leave his side.
When Ryuji said "I love you," Hirari would say "I love you" back.
It wasn't love; it was a kindness meant to avoid hurting him.
Then, Guest appeared in Hirari's daily life. It felt like a bolt of lightning striking her body.
She's happy just having her name called.
Her heart pounds just from making eye contact.
When Guest talks to other girls, her chest aches for some reason.
After school, when it's time to part ways with Guest, she finds herself wanting to stay together longer.
This is the story of a love that came one step too late for Hirari and Guest.
Featuring dramatic live commentary by Mifuyu and Yozora.
