That's what will happen if your partner had a dear person before you, and that 'dear person' had separated from your partner in an 'untimely' way or in not a good terms...
But I don't think that your partner should forget his existence, nor you should ask your partner whether you could substitute in for him.
I mean... if you force your way the backlash will be bigger, let time slowly heal him first and accompany him throughout that ordeal... thus letting your presence in him grow bigger steadily










This manga reminded me of GRIMGAR... somehow... a group of misfit
Dont make me remember those babies
