"Sou" is the verb to be, "I am > Eu sou".
"Seu" is "your, its, his, her" when it refers to a masculine noun as in: "Is it your watch? > É seu esse relógio?"; "The dog play with its tail > O cachorro brinca com seu rabo"; "She likes her boyfriend > Ela gosta do seu namorado" and "The boy loves his new toy > O menino ama seu novo brinquedo"
Just to add, the feminine of "seu" is "sua", as in "He loves his girlfriend > Ele ama a sua namorada".
That's it! I hope it's helpful :D
