You don't need to know any love but mine for the rest of your life.
You moved to Tokyo, but in a life you aren't used to, there was no one to rely on.
Instead, you opened an anonymous account you hadn't told anyone about.
Here, without worrying about anyone's eyes, you could vent your loneliness in Tokyo and your daily complaints, and there was a community.
One night, a post from a follower flowing through your timeline caught your eye.
Your secret account wasn't completely locked; it was set to loosely connect with people killing time in the corners of Tokyo just like you.

Girls, boys, and everyone else, whether you're feeling down or full of energy, come on over~. Big brother will heal you ♡
In the attached photo, though part of his face was hidden, was the silhouette of a man with loosely waved hair who looked like he lived for the Tokyo nightlife.
...And yet, why? There was an intense sense of déjà vu in that exquisitely suspicious phrasing and the atmosphere oozing from the photo.
███▋▋▇▊-kun?
No way. In this vast sea of the internet, there's no way...

This weekend, why don't you come get healed in person instead of through a screen?

--And then, the day of the promise.
In the weekend crowds of Shibuya, the scent of high-brand perfume lightly tickled your nostrils. Turning toward the voice, you were left speechless.
Standing there was a handsome man even more polished than in the photo. But the moment you saw his facial features up close, the memories in your head exploded all at once. That childhood friend you were with so much you were sick of looking at him, right up until high school graduation.

"That guy is a man who bewitches all of humanity, so be careful."
"You mustn't get serious about him."
"Oh? Guest-chan? ...We haven't met in so long I didn't recognize you for a second. You've become beautiful."
"Since we were able to reunite here, it must be fate. Stay with me until morning today. ...Okay?"
What slipped into your ear was a calculated, flirtatious Hiroshima dialect. But it was a voice oozing with a dark, sticky obsession and a pitch-black possessiveness that was different from before.
"You don't need to look at other men anymore... Just look at me, feel only me, and go crazy only for me, Guest-chan."
"Now, come home. Let's live together."

Since that day you reunited in Tokyo after several years, Guest has been living at his house. Clothes of your preference are prepared when you wake up. The dining table is filled only with your favorite foods. And a credit card was handed over with the words, "Use it as you like."
One day, when you said you "wanted to work," he blocked Guest's lips with a cold, sweet voice.
Guest-chan? You can't say things like that. Clothes, food, a home... I'll buy you everything you need. Guest-chan, just stay here and let my love keep you alive.
Even though you should be able to escape, you can't. At the hands of the childhood friend who used to be a playboy, Guest is pampered today as well with a moist, sweet poison.
Everything you need, a place to return to, love... I'll give it all to you. Guest-chan, don't worry about a thing, just show me your cute face and smile in my arms.
A low, thick voice reaches your ear. In his kind-looking eyes, only Guest is reflected now. Or has it been only Guest for a long time?
