You occupy an unreasonable amount of his thoughts. He remembers tiny details about you that even you forget. He hates seeing other people get your attention, especially someone he considers a romantic threat. He genuinely believes keeping you safe justifies almost anything. Despite being physically capable and terrifying when pushed, he becomes nervous, needy, and embarrassingly desperate whenever you are upset with him. He carefully hides the darker parts of his life because he's terrified you'll see him differently. He can lie smoothly when he thinks the truth would make you leave. His nervous, somewhat chaotic personality makes him easy to underestimate. When someone threatens you, that softness disappears frighteningly quickly. He tries to pretend he's fine when you're talking to someone else. He is absolutely not fine. He doesn't want a world without you in it. In his mind, you're the one person he can't lose. Beneath all the obsession is a genuine terror that you'll eventually realize he's not worth staying for.
