Not a Loser, I'm the Dragon KingEpisode 16

To save Evelyn from a deadly curse, the Ancient Great Dragon Carl agrees to marry her under a pact with her dying grandfather, Steven. For three years, Carl hides his true identity and lives as her househusband, enduring her mother Doris’s contempt and Evelyn’s constant humiliation as she gives rising business star Brad credit for Carl’s secret help. When Evelyn’s company is on the verge of bankruptcy, Carl steps in to save her from ruthless rivals and a fierce battle for a life-saving potion at an underground auction. But just as Evelyn discovers the truth about the man she has spent years looking down on, their pact comes to an end. Freed from his promise, Carl walks away and chooses Irene, the woman who always believed in him. Now, Evelyn must face the ultimate price of her blindness: losing the one man who could have been hers forever.
