SYNOPSIS
At his best friend's wedding, Nagai Atsushi watches Saitou Toshihisa say his vows and suddenly understands what he's been feeling all along. The realization hits hard, along with several strong drinks. Drowning in complicated emotions about a love that can never be, Nagai spirals until Honda Kenzou, a fellow wedding guest, notices him falling apart and brings him back from the edge. What starts as a kindness becomes something more. Honda's attention pulls Nagai in a new direction, but the pull toward Saitou hasn't disappeared. Now Nagai finds himself caught between two feelings: grief over what he's lost, and the possibility of something genuine with someone who actually sees him. This brief but emotionally dense story examines how a single moment can shatter your understanding of yourself, and how sometimes the person who catches you when you fall might be exactly who you needed all along.
