All I remember is that the protagonist had a brother who was an omega and had a child with their crush. Their brother runs away after giving birth, so the protagonist takes care of crush and child thinking he is just a substitute.
Thank you so much!
All I remember is that the main character has pink hair? and is the servant of the beloved blond princess with a tyrant dad. the princess isnt as nice as everyone thinks she is and wants the attention on herself and not the other girl. Sorry its not a lot!
