There are scenes you occasionally see in dramas. A married person kissing someone else at the office, or someone waiting for a partner in the military only to end up holding someone else's hand.
I used to watch those scenes and say it was easy. That it wasn't love but an excuse, that it was cowardly. And I believed I would be different from those people.
–Until I met them.
Rael was my first love, and the person I thought would be my last. He was always kind, a man of few words, and he quietly stayed by my side. His soft-hearted and shy nature strangely seemed entirely lovely to me.
And so, time with Rael was always quiet and safe.
