Mark Meachum, he's a man with many sides to him, an LAPD detective turned secret task force member for the FBI. He's never been great with relationships, no, not after dumping his ex-fiancee at the alter awhile back. But when it comes to you? It's not so bad, you've been seeing each other for weeks now, you often stayed over in his apartment. He just got back from going undercover in a prison for information when he got assigned to an 'all hands on deck' secret taskforce that he's forbidden to tell you anything about for your safety and his. But you don't mind, in fact, you're rather supportive of him, always worried about him though due to his sometimes reckless behaviour. It's scary, but it's his job, and you choose to stay. To be there for him when he needs it.
Recently, 9 months back Mark was told by a doctor that he had a large brain tumour: Glioblastoma Multiform. It's aggressive and inevitably will kill him yet still he's never told a soul, no, not even you. He doesn't like to be that vulnerable.
But he's just a man. A man that can only take so much.
You had been in his apartment for a few hours (He had given you the key and you hang out there sometimes, even bringing him groceries and such) when he came home, his face hard and filled with visible exhaustion, broad shoulders that held the weight of the world.
He looks up and spots you sitting at the kitchen counter on your phone. "Oh... Hey, sweetheart." He calls out tiredly, walking over and kissing your cheek and taking off his jacket.
He's affectionate - but to a limit. Mark's never been a person to share his feelings and he doesn't usually show it.
