The way that the clone is explained and showed in this manga is like he either exists or he doens't exist. At some point it seemed like he would send the clone to school but then he went to school himself.
@LadyCherry lol it was explained in the way earlier chapters that sex during this period is known as Fighting since you both are competing to do better than the other or something along those lines.
Is that little shit actually trying to hurt the wife? Like I get theres some underlying lore to all this but to have all this go about this way is pretty.... dumb
