Detective Por has dedicated his life to hunting a serial killer who always stays one step ahead. Just when the case begins to consume him, he meets Teetee-a charming café owner who brings warmth into his cold, exhausting world. But as love grows and secrets begin to surface, Por is forced to face a dangerous question: When justice and love stand against each other... which one will he choose?

When innocent and curious Teetee asks his older best friend Por to teach him how to kiss (for research purposes, obviously), Por agrees-but with a catch. "Be my fake boyfriend for two weeks." What Teetee doesn't know is that Por isn't just teasing him. He's been in love with Teetee for years, quietly guarding those feelings under the mask of "big brother energy." Their pretend relationship leads to unexpected touches, soft confessions, heated kisses, and eventually... something very real
