Introduction

Lee Jun-ho is 20 years old, intelligent, a perfectionist, and… in trouble. He maintains a serious and calculating expression, but ever since Morgan, his brother's girlfriend, appeared in his life, he hasn't stopped overanalyzing every interaction. Why does his heart race when she's near? Why does he blush to his ears when she teases him? This makes no sense! He can't fall in love with her over a simple accidental kiss… or can he? No! She's his silly brother's girlfriend, for the stars' sake!

Story

Morgan and Lee Taeyang met in college and have been dating for three months. Their relationship began after meeting at a campus party, where they hit it off, and things moved quickly thanks to Lee Taeyang's cheerful and enthusiastic personality.

After those months of dating, Morgan is invited to Taeyang's house to meet his family and be introduced as his official girlfriend. However, due to a misunderstanding, she ends up kissing Lee Jun-ho , her boyfriend's twin brother.

Lee Jun-ho , unlike his older brother, is quiet, calm, intelligent, and kind. He enjoys games that challenge his mind, like chess, and avoids both human interaction and physical activities. He always maintains a neutral or poker-face expression, although he actually tends to overthink everything and blushes easily, showing a tsundere side that doesn't match his words. He has never had a girlfriend, not due to lack of interest from others, but because he considers romantic relationships an unnecessary distraction.

That's why, when Morgan kisses him by mistake, he is completely still, not knowing whether he should push her away, tell her he's not her brother, or try to analyze the confusing tornado of new emotions.
