Socks, every Monday at the same time. Today it's two black socks.
How does Lee Jieun react when Sunhee asks if she comes on Mondays?
Show answer
Her face goes red. "네... 아니, 가끔 와요." (Yes... no, sometimes.) Then she quickly starts the washing machine.
What does Sunhee find in the corner at the end of chapter 1?
Show answer
A blue bag, with a few wet socks next to it.
What does she find inside the blue bag in chapter 2?
Show answer
A child's drawing of a mother and child together, and a small note: "엄마 양말을 신어요. 미안해요."
Who has been taking the socks?
Show answer
Jieun's son. There are no socks at home, so he takes them from the laundry room before school. Sunhee's response is to ask Jieun if she is all right.
Grammar to notice: polite -아요/-어요
The narration is in plain -다 forms, but the conversations use the polite -요 style that beginners learn first. To make it, take the verb stem and add -아요 (after ㅏ or ㅗ) or -어요 (after other vowels); 하다 verbs become 해요. The first exchange in the laundry room shows politeness at work: Sunhee, the elder, asks in casual Korean, and Jieun answers with 요.
너, 월요일에 여기 와?
Neo, woryoire yeogi wa?
You, do you come here on Mondays?
Casual: 오다 → 와, no 요. An older woman to a younger neighbour.
네... 아니, 가끔 와요.
Ne... ani, gakkeum wayo.
Yes... no, sometimes.
Polite: 오 + 아요 → 와요.
엄마 양말을 신어요. 미안해요.
Eomma yangmareul sineoyo. Mianhaeyo.
I wear Mum's socks. Sorry.
신다 → 신어요; 미안하다 → 미안해요. The note in chapter 2.
아들이 양말을 가져가요.
Adeuri yangmareul gajyeogayo.
My son takes the socks.
가져가다 → 가져가요: the stem already ends in ㅏ, so the two merge.
이지은은 빨리 세탁기를 돌린다.
Ijieuneun ppalli setakgireul dollinda.
Jieun quickly starts the washing machine.
For contrast: the narration's plain form. In speech this would be 돌려요.
In chapter 2, Jieun's apology rises a step further to the formal 미안합니다: she is very sorry, and very embarrassed.
Reading Monday's Little Secret at A1
Older neighbours are addressed by family titles: 박 할머니 (Grandma Park) and 김영호 할아버지 (Grandpa Kim Youngho). Ages come with 세, as in 67세 (67 years old). These are the forms you'll hear in any Korean apartment building.
The clues are easy to follow because each one is a plain object with a colour: 검은 양말 (black socks), 빨간 가방 (a red bag), 파란 가방 (a blue bag). Keep track of the colours and you can play detective alongside Sunhee.
Chapter 2 is gentle rather than dramatic. The thief is found, but the real question at the end is a kind one: whether Jieun herself is all right.
Frequently asked questions
Is this story really A1 level?
Yes. It uses short present-tense sentences and everyday words such as socks, laundry room, bag and Monday. The dialogue uses the polite -요 forms most beginners learn first.
How many chapters are there?
Six at A1. Chapters 1 and 2 are free here and in the app; chapters 3–6 are part of Contos Premium.
Is it a dark crime story?
No. It's a small neighbourhood mystery about missing socks, with a kind ending to chapter 2 rather than a villain.
Why does Sunhee speak casually to Jieun?
She is older, so she can use casual Korean (반말) with a younger neighbour, while Jieun answers politely. Age decides a lot about how Koreans speak to each other.
