You Were Supposed to Watch Your Cousin, Not Raise Her Like a Girlfriend!

When Wen Mo agrees to let his distant cousin crash at his place, he expects a few awkward weeks—not a full-blown domestic life with a clingy, emotionally guarded girl who treats him like her entire world. She doesn't smile. She doesn't make friends. But she clings to his arm like a lifeline and declares he's all she needs. What starts as a simple favor spirals into an unexpectedly tender slice-of-life romance as Wen Mo finds himself raising—no, nurturing—a girl who's slowly learning to open her heart. One small smile at a time.
