Don't bite me, Senior

Nerine has suffered years of abuse from his uncle, aunt, and cousin. On his eighteenth birthday, when he should claim his father's trust fund, they try to imprison him. Severin, the mysterious senior he has recently begun dating, rescues him. Severin is gentle, but he hides that he is a 1,400-year-old vampire. When Nerine discovers this, he feels betrayed and nearly gives up. Severin reveals that centuries ago, Nerine was a prince, and Severin was his knight and lover. He has searched for him through every lifetime. Nerine slowly trusts him again. With Severin's support, he proves his relatives stole sixteen million dollars. They are imprisoned, and Nerine reclaims his inheritance and father's company. Vampire hunters attack, and Nerine saves Severin with his own blood. When hunters close in, Severin agrees to leave for safety. Nerine runs after him, kisses him publicly, and promises to find him.
