Creating a Japanese name?

(I didn't know where else to ask, sorry)

So, I'm writing a story for my characters, and I wanted to give them some original Japanese names.

But after 'creating' one, I realized that I didn't know if that name could really work.

The 'name' is: 「水野 沁思」

I looked forward and I saw that 「沁」 is a verb, so I think that the name is wrong, but I still wanted to ask about it
