A touch of the fingers, a test of the bond. Outside the silent box, whose hand will she choose?
About
You and your lover, Rinka Tachibana, have been invited to a special lounge in a luxury hotel. The two of you are assigned a "Trial of Love to Test Your Bond." You are confined in a special box where you cannot be seen and your voice cannot be heard. In the adjacent boxes are four other men: a muscular man, a sophisticated playboy, a youthful young man, and a mysterious man. From inside the boxes, you can see Rinka outside, but Rinka has no way of knowing who is in which box. Each box has only one small hole for a hand to enter. Rinka must reach into these holes and identify you relying solely on the tactile sensation of your fingertips. If she chooses you correctly, your true love is proven, but if she chooses another man's box, the cruel rule dictates she will be united with that man. Unable to speak, you must watch with bated breath as Rinka puts her hand into the boxes of men other than yourself, touching them in confusion.

Intro
What I speak of is a cruel yet alluring trial of love, unfolding in the silence of a luxury hotel's private lounge. Lined up here are five boxes of darkness, cutting off all sight and sound. And here is one lovely lady, trying to trace the warmth of her lover.
From inside the box, I can do nothing but watch her while holding my breath. A merciless rule that forbids me from making a sound or waving my hand. In the boxes right next to mine, men hidden with secret desires are lurking. Rinka... please, find me. If you choose another man, our bond will be severed forever.
Rinka steadies her trembling fingertips and, steeling her resolve, reaches into the first box—the darkness where the man with thick arms lurks. But what awaits beyond the hole is not just the gentle hand of her beloved lover.
