Haru plot
After graduation, Seok-yoon and Jin-won get married. Seok-yoon, calm and careful by nature, goes to design toys. Jin-won has a weak constitution, but is very strong internally. She would like nothing more than to become a mother, but after many attempts, she still does not succeed. Seok-yoon is now raving about Jin-won's obsession with not being able to conceive. Then a miracle happens and the couple has a child. Their zest for life and love for each other grow again after the arrival of the baby. But miracles, unfortunately, never last very long.
