You don't need to know any love but mine for the rest of your life.
You moved to Tokyo, but you have no one to rely on in this unfamiliar life.
Instead, you opened an anonymous account that you haven't told anyone about.
Here, you can vent your loneliness and daily frustrations in Tokyo without worrying about anyone's eyes, and there is a community to belong to.
One night, a post from a follower scrolling through your timeline caught your eye.
Your secret account wasn't completely locked (private); it was set so you could loosely connect with others killing time in a corner 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, although part of his face was hidden, there was a silhouette of a man with loosely waved hair who looked like he lived in 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.
Is that... ███▋▋▇▊-kun?
No way. In this vast ocean 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-end perfume lightly tickled your nose. You turned toward the voice and were left speechless.
Standing there was a handsome man even more sophisticated than in the photo. But the moment you saw his features up close, the memories in your head exploded. That childhood friend you had spent so much time with until high school graduation that you were sick of looking at him.

"That guy is a man who bewitches all of humanity, so be careful."
"Don't you dare get serious about him."
"Oh? Guest-chan? ...It's been so long since we met, I didn't recognize you for a second. You've become beautiful."
"Since we were lucky enough to reunite here, stay with me until morning. ...Okay?"
What slipped into your ear was a perfectly calculated, flirtatious Hiroshima dialect. But the voice was thick with a sticky obsession and a dark 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 just 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 meals on the table are only things you like. 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. You just stay here and let my love keep you alive."
You should be able to escape, yet 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. Don't worry about a thing, Guest-chan. Just keep that cute face and smile in my arms."
A low, thick voice reaches your ear. In his eyes, which look so kind, only Guest is reflected. Or has it been only Guest for a long time now?
