Need help with a unisex or male name for a character!

I’ve just started writing a new book, and I’m not sure what to name my character. If anyone could help that would be great. The name can be unisex or male, just not female because I have plans for this character and i would rather they not be female (it would mess with the relationships i have planned)

the character’s personality is shy, and they own a bookstore. they are also imaginative and drawn to water and earth. They are also easily frustrated but still kind and accepting. [name_m]Trust[/name_m] is not something that is given to anyone they meet and they are very introverted. I think this character will possibly be more unisex then male.

If anyone could help I would be very grateful! Thank you!

[name_u]Lucca[/name_u]. 100% [name_u]Lucca[/name_u].

[name_u]Sam[/name_u] could be short for [name_f]Samantha[/name_f] if it’s a girl and [name_m]Samuel[/name_m] if it’s a boy, or [name_u]Alex[/name_u], which can be short for either [name_f]Alexandra[/name_f] or [name_m]Alexander[/name_m]. You could even do [name_u]Kelly[/name_u], if she’s of Irish descent.
