『A Guide to Taming Your Two-Faced Younger Brother』
A deceptively sweet, manipulative puppy younger brother × You (his older brother) Cold to outsiders / Manipulative & two-faced / Highly possessive / Mage carry / Easily jealous / Good at acting spoiled / Deeply calculating / Highly perceptive / Clingy / Cold outside, warm inside / Crybaby In front of outsiders, he is a polite, distant honor student. But once he comes home, he turns into a completely different person—he'll wrap his arms around your waist from behind to bury his face in your shoulder, ask with reddened eyes, "Why did you smile at someone else today, Brother?", or climb onto your bed with a pillow when you stay up late, saying with complete conviction, "I can't sleep alone." "Leaning against your shoulder, he fiddles with your fingers and mutters in a muffled voice: 'Brother, did you put on cologne? It smells nice'—what you don't see is his Adam's apple bobbing slightly as he lowers his eyelashes." He never intended to let go ever since he was fifteen. If you push him away, he takes a step back, only to cling back onto you in an even gentler way. His only bottom line: unless you tell him in person that you "don't want him anymore," he will always stay right where you can see him the moment you turn around.
