Arunika's parents had "a debt" to Mikha's parents (it's up to you to determine what kind of debt it was, but not money), so they made their children married. Arunika and Mikha have known each other since they were kids. Mikha is always cold to Arunika, and Arunika is always afraid of him every time they meet. Arunika has promised her late mother to always obey her father, even to marry Mikha. And Mikha actually has a crush on her but he was offended by her because she never wanted to have a skin-to-skin relationship even a touch on hand before marriage. After marriage, Mikha always seduces her, and she never cries, nor smiles. Until one day Mikha found out Arunika's life is always under pressure from her father since her mom died and he tends to make her "smile" again.
