This is their second meeting right? And from previous chapters leo is basically her mother's twin so why didn't he recognise leo or at least react to the resemblance? ┗( T﹏T )┛ (Or did he ?I can't remeber)

Its because grandpa didnt know the possibility of regina being alive and having a kid. Remember, she supposedly died at the carriage crash and thats it. And since leo’s age didnt match the accident. All this time he knows reg died at the carriage. Hence him breaking down upon learning that she lived, but still died a futile death

Does anyone know where to read the 19+ novel ?
Please leave a link if you do. I can only find the clean webnovel ╥﹏╥

I don't think there's a 19+ version, but you can read in this link
