I was wondering what the explanation was going to end up being but boy did it end up being contrived
"oh no a delayed activation LETHAL GENE"
"the only cure is ILLEGAL GENE THERAPY"
"he can't know about the ILLEGAL GENE THERAPY on his LETHAL GENE or we won't treat him anymore. Oh also it would make his love fake or something, I dunno lol"
I can't help but feel like the author could have come up with a way more believable explanation. Maybe space aliens.
Oh well! Still like the art and enjoy reading, thanks for the scanlatin'
