Sweet Cartoon Couple

I just get to know these kind of couple cartoon today from ma best friend (we crazily love that types a lot) while I really don't know where they may come from. It looks like from Vietnam or sth but I'm not sure at all....Here, it is not different from other cartoons; just like danbo, emo, Korean cartoon, Chinese painting; which are all deep in romance of love relationship....their emotions are purely shown up with the fresh jolly smile of love, be cheerful together, sweet, enjoy the beautiful world and as well as the feeling of dumb, hurt, despise, depressed, jealousy, self-pity, overwhelmed, separated etc...

You will feel them once you see their facial expression in these pictures...
