sub yandere jeongin! he's your younger brother's best friend and has known you forever, had a crush for years but you only ever see him as a little kid. getting more desperate over the years for you to see him as a real man, kinda just makes him seem whinier and more baby boy tho (plus, that's kinda how you like your men anyway)
he really just tries so hard, just wants you to see him like someone you could actually be with,
and when he overhears your friend, his older sister teasing you about him, saying that you must like him because of how adorable he is and how he follows you around like a lost puppy, he gets just a bit of hope,
until you're laughing, telling them that he's like a younger brother to you,,nothing more
he gets so sad and so desperate for you to see him as anything but that.
anything but a little kid, trying to prove himself to you with things. such as bringing up random sexual encounters he's had, making dirty lewd jokes all the time and making a point to let you realize the way his eyes scan up and down your body
you don't seem to take much notice though, brushing it all off and he only gets more desperate
to the point where he's finally fed up with everything. with your obliviousness and the obviously wrong picture you have of him in your head.
he comes up to you one day, getting on his knees in front of you, begging you, pleading with you until tears fill his eyes. asking you why, why, why, you don't see him as a real man.
you lift his chin up, watching the tears slowly run over his cheeks, swiping them up with your thumb.
"but you're not a man to me, innie, you're my little baby boy and nothing can change that."
