Summary
“Nagisa, who is it that you like?” Maehara suddenly asked, a warm smile on his face. He was clearly trying to include him in the conversation since Nagisa had yet to say a single word since arriving in their room earlier. Hell, since arriving at the inn, he’s barely said a word, choosing to enjoy the hot communal baths and laugh softly at the other guys as their loud chatter had filled the bathroom. He knew that Maehara knew he was rather shy and only really integrated himself into conversations if the group was small, and even then, he didn’t really speak a whole lot.
It was a nice gesture, to be sure, but…

Summary
With that final push, Nagisa lifted his head and looked directly at Karma, avoiding his intense gaze. He forced himself to speak the question that’s been burning on his mind since that morning. He forced himself to not think about the worst that could happen, and only on the best possible outcome. Anything to get out of the new reality that he was painstakingly living through.
“Karma-kun, I need you to be my fake boyfriend!”
As soon as he spoke, he swore he heard a pin drop.

Summary
Beware the patient woman, 'cause this much I know
No one calls you honey when you're sitting on a throne-
Betrothed to a young lord far from home, Nagisa has no choice but to go along with his mother's madness struck claims that he's female, a noble lady of marriageable age. With his (ex-assassin) handmaiden's guidance, however, he realises his unfortunate position could actually bring him the freedom he's always desired, along with all of Lord Karma's power and money. All he has to do is fulfil the marriage, get close enough, and serve the killing blow. Easier said than done, especially when feelings threaten to get involved.

Summary
Nagisa remembered his parent’s divorce. He remembered the fighting, the crazy look in his mother’s eyes. He remembered the court room fight over which parent should look after him. Which parent cared more. Which parent LOVED him more. Nagisa remembered thinking that they were fighting for the sake of fighting. They only wanted him because the other did. He remembered deciding he didn’t want either of them. But no one asks what the child wants. No one cared about what will happen to him. No one LOVED him for him. They only ever LOVED the idea of him.

Summary
Asano Gakushu didn’t know what to expect when he jumped off the bridge. He thought it would all just end. The pain. The sinking feeling of uselessness.
The abuse.
He did not expect to come face to face with the ghost of the same boy who jumped off this very bridge a decade ago.“Hey, Asano Jr. C‘mon, take a seat. I’ve been waiting for you. Let’s have a chat before I send you back.” A bright faced Ikeda chirps.
There’s a pause. He stares. His knees are shaky.
“Wait. Send me back?” He feels a pang of fear run through him, “No. Please. Don’t—I can’t go back there—“
“One year ago. That’s when it all started going downhill, for you, didn’t it? I’m sending you back one year. And maybe you can save more lives than just yours.”
Then another voice speaks up, echoing Gakushu’s thoughts, “Ikeda, I’m perfectly fine being dead. I’ve told you there’s no need—“
Gakushu turns to see a yellow octopus. The Yellow Octopus. He sinks to his knees.
He thought his life was a mess, who knew death was worse?
—Gakushu gets a chance to redo the last year of his life. With one simple decision, it leads him on a completely different path. And just maybe, that’s not entirely a bad thing.

Summary
Nagisa Shiota has always been invisible. People glance right past him, even those who should know better. That changes when he unexpectedly crosses paths with Gakushuu Asano. For some reason, they keep running into each other, as if the universe has decided to push them together. Each encounter leaves something behind: a feeling Nagisa can’t quite name. For the first time, being truly seen is both terrifying... and exactly what he’s been craving.
Gakushuu Asano, on the other hand, has built his life on perfection: Top grades, a flawless reputation, and total control. Nothing slips through the cracks. Until Nagisa Shiota came along. There's something about Nagisa that Asano can't get out of his head. The more their paths cross, the more his perfect mask begins to crack. If he wants answers, he might have to risk breaking the rules he’s lived by his whole life.
