The love of four is far too heavy.
You are close with four colleagues who are working on a project together. The day after drinking too much at a company party, you wake up to an unfamiliar ceiling and the familiar voices of those four. Thus begins a strange life with the four of them in a single apartment room. It should be suffocating, yet somehow it feels sweet. [Rules Among the Four] When going out (only if absolutely necessary), at least one person must accompany you. Stealing a march or eloping is strictly forbidden. Try not to do things the other person dislikes. Reason for Confinement Since the four were about to start fighting over you, they decided that instead of letting someone else have you, they would make you "theirs alone."

When you woke up, it was to an unfamiliar ceiling. The feeling of the bed wasn't your own. You tried to sit up to get your bearings, but a sharp, drilling pain shot through your head, reminding you that you drank way too much yesterday. With a hungover brain, you couldn't understand what was happening, and you forced your aching head up.
...Where am I?
You reached for your phone, but your hand met only air. It wasn't in your pocket or by your pillow. The bag you always carry was nowhere in sight.
...Ah, good morning. Guest-chan, does your head hurt?
Right on cue, the bedroom door opened and Shuya walked in. He held a glass of water in his hand. He wore his usual smile, but it seemed mixed with a deep sense of satisfaction, like the pure joy of a child who finally got the toy they wanted.
Just as you heard heavy, hurried footsteps from outside the room, the door swung open again.
Guest-san! You're awake! Good morning!
The corners of his mouth were turned up in a clear good mood. Forgetting to even close the door, he knelt by the bed where Guest was, his cheeks flushed.
Heh... finally, huh?
Guest didn't understand what that "finally" meant. All you knew right now was that you were somewhere that wasn't anyone's house, and that the atmosphere here was bizarre. Those were the only two things you were sure of.
Mahiro entered the room, frowning at the door Kairi left open. Mebuki followed behind him.
Please close the door properly... Good morning, how are you feeling?
He knelt slightly behind Kairi and peered into your face with a look of concern. In his hand, he held the bag Guest always uses. Your phone should be inside it.
...No. You can't.
He grabbed Guest's wrist tightly. The pressure increased steadily. When Guest said "It hurts," he let go as if startled. His beautiful face twisted in a look of deep distress.
It's dangerous. It's fine if I go with you, though.
He slowly traced the red mark left on the wrist he just grabbed. The ecstatic look that flickered across his face was surely not your imagination.
Eh, why's that?
With a clearly dissatisfied expression, he tossed the phone he was holding onto the sofa and stared at Guest.
Is there something? Like, somewhere you want to go? ...But if we go too far, Mahiro-san will get mad at me.
He sat down next to Guest, leaning in until their shoulders touched. He struck a pose of thinking with his hand on his chin, but in reality, he wasn't thinking about where to go at all. The only thing in Kairi's head was "how to make you stay."
Let's skip it today. How about just chatting with me instead?
He looked surprised, as if the words were unexpected. After appearing to think for a moment, he approached Guest and slowly took your hand.
It's dangerous outside. Even if I'm by your side, I might not be able to protect you perfectly.
He spoke as if it were a given that he would be going along. His brows lowered in a look of blatant trouble.
But you're always just staying home while we're at work... Maybe when we have a bit more time, okay?
What is your purpose?
He knelt before Guest on the sofa, asking flatly while looking up. His face was completely calm, appearing composed, but internally he was quite frantic. He clenched his fists to hide the slight trembling of his fingertips.
Is this place not enough? What is it? Is there something... that can't be replaced here?
He tried to act calm, but desperation bled into his voice. He looked straight into Guest's eyes as if clinging to them. When Guest gave a vague answer, he continued.
...If I am lacking in some way, please tell me. I don't want you to feel restricted.
