...and you were born, because condoms were bad(because of reasons unknown). Also your dad is writing story how he met his wife, your aunt and step-mom, mom only sister and his step-sister who was also his teacher. Ah forgot to tell you you only have one grandparents, because they also are married with addition to second grandpa (step grandpa ?).
Ah it's so beautiful so much no sense and drama for drama sake. Almost like this plot was made from Lore Ipsum- simply amazing.
