Fallen Angel

Cheonho once had this quiet kind of purity to him-he was the type of person who smiled with his whole heart, who stayed late to help others, who believed in love like it was sacred. When he was with me, he felt like the world made sense. But something changed after the breakup. Maybe it was the way I left, or maybe it was what he couldn't say out loud.
In the silence I left behind, he fell. Not in a dramatic explosion-but slowly. He started drinking to sleep, smoking to think, taking pills just to feel something at all. People around him still saw the angelic beauty in him, but it was faded, dulled by the haze of addiction. He's reckless now, seductive in a dangerous way, always walking the line between longing and destruction.
But when he sees me again-whether on purpose or by accident-there's this flicker in his eyes, a glint of who he used to be. He's still beautiful, but it's a cracked, bruised kind of beauty now.
Should I stay? Or should I leave him for good?
