Read Nankuru Nee-san Don't Worry Be Happy ; なんくる姉さん ; 没关系姐姐
Issa Kinishi, known as Nankuru Nee-san, is an overly cautious young man who constantly frets about every little detail in life, living in a way that avoids any conflict or trouble. His days are spent in quiet unease until he crosses paths with a mysterious, sun-kissed girl who defies all his expectations.
She carries a phone with a shattered screen, walks into eateries without checking reviews, and cooks curry without a second thought for the splatters on her outfit. Her carefree attitude fascinates and unsettles Issa so deeply that, without realizing it, he finds himself drawn into her world—watching her from a distance, unable to shake her from his thoughts.
Her presence lingers in his mind, disrupting his usual routines and pushing him toward actions he never imagined taking. The more he observes her, the more his anxiety and curiosity intertwine, blurring the line between harmless interest and something far more unsettling.
Issa’s once predictable life spirals into uncertainty as he grapples with emotions he can’t control. The girl, unaware of his growing fixation, continues living freely, leaving him both enchanted and tormented by her indifference.
What starts as mere curiosity soon becomes an obsession, pulling him further from his cautious nature. The cracks in his composed facade widen, revealing a side of himself he never knew existed—one that’s reckless, desperate, and utterly consumed by her.
Their worlds couldn’t be more different, yet he can’t escape the pull she has over him. With every passing day, the distance between them shrinks, but so does his grip on reality.
The stains on her clothes, the unrated restaurants, the broken phone—each detail etches itself into his memory, fueling his silent pursuit. He tells himself it’s just fascination, but deep down, he knows it’s something darker, something he can’t name.
And so, Issa’s harmless existence unravels, thread by thread, all because of a girl who lives without hesitation—while he watches, helpless, from the shadows.
