There’s nothing extremely particular in the gif by the Japanese Illustrator Nimura Daisuke, nothing crazy, nothing complicated.

Nimura Daisuke’gif are simply beautiful in their simplicity.
His main characters are boys and girls, maybe young students, struggling with life.
Sexuality, sport, school, friends, cats.
Normal lives, made of ordinary days but especially of small gestures that form them.

If you want to see all his work you can find them here.
