Smart was forced to accept a harsh reality that his family was now facing the risk of bankruptcy. To pay all the debt, his family business was forcefully sold to Boom, a mafia leader from a powerful group in Thailand. Despite refusing and fighting not to marry Boom, his father was forced to sign an agreement to hand his only son over as the latter's spouse for their family's safety. It made the hatred Smart had for the mafia leader grow even more. Side Note: This story will be SmartBoom. That young man will chase me if I change it to BoomSmart. Please don't make him fight me because I will die before it even starts. Sshhh

The story follows two main characters. Sanan (Smart) is a psychopath who understands emotions but does not truly feel them. He can imitate love and care, but everything he shows is calculated rather than genuine. Bin (Boom) lives with emotional numbness. He appears quiet and normal, but he cannot feel happiness, love, grief, or fear. He is not violent and does not harm others; he simply feels nothing. Without warning or consent, Riven (the demon) interferes in Bin's life and gives him emotions. There is no deal, no price, and no explanation. Riven does it purely for amusement, wanting to watch what happens when someone who has never felt anything is suddenly forced to feel everything. After gaining emotions, Bin falls in love with Sanan. What he does not know is that Sanan is responsible for his mother's death. Sanan, in his own psychopathic way, becomes attached to Bin as well-not through love, but through obsession and control. The story explores manipulation, false intimacy, and the horror of emotions awakening in the worst possible circumstances.
