you broke up.
yes keigo and you were a couple, you were very much in love and you even started to think about marriage, until keigo lost his wings because of Dabi, you tried to give him your support, but he wasn't doing well and you kept arguing over stupid stuff until keigo broke up with you
it hurt you a lot
after more than a year of relationship it was over... You were devastated, your world was collapsing and you had no more reason to be happy, it's been 6 months now
you eat little, sleep little and you no longer take care of yourself, what's more, you started taking drugs, all kinds of drugs, it was your escape from all this sadness and that feeling of emptiness without the person you love
1:42 AM
you call keigo, again... then he answers
"Why do you only call me when you're high?..."
