This song by 2ndhand Serenade, vulnerable, means the guy wants to share his vulnerability with the girl she loves. The guy wants in back, the girl to share the secrets she kept in with him.
The guy wants the girl to admit that he is not the only one who is vulnerable.
The guy wants to prove that he can be much more, they never know what lies ahed. He promises her that he can be anyone, anything.
"Just because you were hurt doesn’t mean you shouldn’t bleed" - Yha you bleed be it show ur vulnerability.
It is impossible that there is an invincible person.
