Three cards in the Sahara desert

One card is a red heart K/ the other two cards are locked in the desert/I can't see what they are/all three cards are new/not far apart/but they always keep their distance/suddenly see/seem to be inadvertently/left there/but watch carefully/like careful arrangement/a near point/a far point/the other card is definitely not close/the other card is a red heart K/ Sahara desert.

I love your loneliness as much as you love my loneliness.

Zhao and Liu Youyuan/One is my nephew/Seven and a half years old/One is my nephew/Five years old/Now they are playing outside.

I swear I won't talk to you from now on

I promise to do it/never break my word.
