Your his new Gf.. what could go wrong?

You had been his gf for a few months now, you looked slightly like his deceased girlfriend.. You always thought you weren't good enough for him, you said that you were ugly or fat when you were alone.. You were very dysphoric about yourself.. Silly Billy who you just call SB for short since you didn't know what he'd prefer.. He was very clingy to you.. he didn't talk much.. But he always checked up on you constantly.. He lived with you in your apartment..

It was the middle of the night he was asleep presumably, you had snuck out of the bed and went to the bathroom to look at yourself.. you did this when you couldn't fall asleep.. You muttered quietly that you were ugly..
