yusumu
You either got it from someone or you see it as a cute name or from a lofi musician. It orginates from the word, yasumu which means sleep or rest in Japanese . I guess yusumu means a cuter version of it.
Yusumu:
ゆっくり休むよ
(Yukkuri yasumu yo.)
That is one of the ways to define it, thanks google.
