Guy: “You look beautiful.” *finger on cheek*

Girl: *blushed* kamsahamnida (thank you)

Girl: “I wish I can see you.”

Guy: “Me too.”

Girl: “I love you.” (this is cute because this is supposed to be signed with two hands (palm over the thumb) but with one hand holding the iPhone, one hand is being signed.)

Guy: “I love you too.”

Pretty universal, isn’t it? ^^
