I think hes still kidnapped
poor him, forgotten xD
(≧∀≦) I love your comment cause your right he has been forgotten
IF I remember correctly, the FL once said grandpa's case has been "done". Like on progress?? Idk whether it means she has sent rescuers OR the gramp is simply safe but hidden so he can't be attacked again...
But yes, I do think the author-nim forget him either completely or partly like "which scene should I make his comeback on?" (≧∀≦)
Wasn't he kidnaped by his old lover an thats why she's not really worried?
What happened to Grandpa?
