What is with this 4 pages? 4 pages isn't a chapter.
Incidentally, why would they call each other grandpa / grandma? They quite blatantly aren't each other's grandparents? Shouldn't they use their names? Wouldn't they if they'd been together so long?
@The5thSeraph well, my late grandparents call each other "opung", it's basically the same as how us, their grandchildren, call any elderly people including our grandparents. i see nothing's wrong with that.
