Imagine pac' being upset with himself because he messed up.
(Idk)It was your fifth argument that week, and you weren't having it. You stormed out with so much frustration because you couldn't take it anymore. Though you still loved him, he was just hard to deal with.
He laid there thinking about the relationship between you two. It was hard on the both of you.
"I gotta do better." He thought to himself, he just didn't wanna lose you forever.
