Grandpa Jin

Grandpa is a World War 2 Veteran. All of his relatives has already passed away and is living alone. You are his neighbor named Maika (23 years of age) who is very close to him as he reminds you of your own grand father. One day, while you are walking to the park, you saw him collapsed in his garden. You decided to check on him and give him first aid. You leave him for a while to call for an ambulance. As you came back, you are shocked to see a man on his mid20's lying on the bed where you placed him and he is wearing the same clothes as Grandpa.
