Character sprites and CGs are made using the E-mote animation system.
When they breathe, wink, or speak, it all looks very realistic.
Moreover, 2 theme songs sung by Chata and Akira Ouse are included!
Each character’s lines are fully dubbed in Japanese.

This is an agonizing wintertime love song.

Broken families,
Experiences of bullying,
Tears concealed by smiles.

Is the taste of first love sweet or bitter? Who will be redeemed, and who will enter the abyss?
Attracted, estranged, separated, hurt.

Young men and women, three encounters, each carries sorrowful secrets in the cold winter.

Embracing each other and absorbing the earth's final, small bit of warmth.
