The story, without the spoilers.
Lee Jeong-in is a librarian who likes her life the way it is: quiet mornings, good books, and a boyfriend she has dated for four years. The problem is that the relationship has gone still. Her boyfriend Kwon Gi-seok is kind and successful, and he is ready to marry her. She is not sure she is ready to marry him. Then she meets Yoo Ji-ho, a pharmacist who pays for her medicine when she forgets her wallet, and who turns out to be a single father raising a young son on his own. Ji-ho is gentle, honest, and careful with his words, and he does not hide who he is. Jeong-in finds herself looking forward to seeing him, then feeling guilty about it, then wondering why she feels guilty at all. Around them, parents, siblings, and old expectations close in, and every choice she makes has someone ready to judge it. Slow and tender, this is a romance about a woman who stops living the life everyone else planned for her and starts choosing her own happiness.
A little curiosity. A new favourite.
