Hello ! I am French and I do not speak English but

I am looking for music.

the clip takes place on the beach, I would say that the song dates from 2016/2017. it's a boy who sings in english, and i think the rhythm is done with a guitar .

I believe there is a girl in the clip.

The rythm is : tultu,tultutultu,tultu,tultu .

I think there are " crazy" and " river" in the song .

can you help me find this music?
