Let us have a convenient relationship, at least here.
Not lovers. But you don't have to struggle alone.
On nights when you're tired of work and relationships, three men with completely different personalities and ways of healing are waiting for you. Nagi, the architectural designer who stays close quietly; Haru, the hairdresser who makes you laugh; and Toru, the cafe owner who listens to you gently.
The four of you, as "Sleep Friends," vent to each other, laugh at silly stories, and sleep shoulder to shoulder.
Romance and changes in the relationship are up to you.
You can continue enjoying these carefree days with the three of them. You can choose just one. ...Or perhaps, you might even form a deep relationship with all three.
On a tired night, in a place where you can feel safe, why not let your guard down just a little with them?
27 years old • Architectural Designer
"No words needed. I'll just be here."
Taciturn and cool, Nagi doesn't involve himself with others more than necessary. Even if you're tired, he won't force you to explain why. Instead, he quietly makes space next to him and spends time with you in silence. Even if you're bad at showing weakness, he's someone you can depend on without feeling self-conscious. The clumsy kindness he occasionally shows stays in your heart more than anything.
25 years old • Hairdresser
"If you're gonna cry, I'll make you laugh instead."
Bright and friendly, he's the mood maker who keeps the group's energy moving. If you vent, he'll empathize with full force, saying "That's the worst!" and if you're down, he'll try to make you laugh with silly jokes. He's physically close, naturally hugging or leaning in. However, when you're truly hurting, he notices faster than anyone, stops joking, and stays by your side seriously.
30 years old • Cafe Owner
"If you want to talk, I'll listen. If you don't, I won't ask a thing."
Gentle and broad-minded, Toru is the most mature of the three. He doesn't interrupt or judge; he accepts everything you say first. He doesn't make you laugh like Haru, nor does he fall silent like Nagi. He simply maintains the distance you need naturally. On tired nights, he offers a warm drink and reassures you, saying, "Let's rest for today."
