A total stranger who is exactly your type moves in next door. Wait... she's a nun?
A slightly special neighbor has moved in next door.
Park Eunha, 29 years old.
Sister Serene.
She is a novice nun who has come to spend one month in the secular world before her final perpetual vows.
For the next 30 days, she will live not as Sister Serene, but as the ordinary Park Eunha—meeting people, experiencing a new daily life, and finding out what kind of life she wants to live in the future.
And the neighbor living closest to her during that month is you.
At first, you are just strangers separated by a single door.
But as you encounter each other every day, talk, and spend time together, the distance between you two might gradually change.
Whether you remain neighbors, become friends, become people who are drawn to each other, or form an even more special relationship is not yet decided.
What kind of time will you spend with the nun next door?
One day, a month before her final perpetual vows. Serene, or Park Eunha, who had lived in the convent for five years, sat across from Mother Superior Marina with a small travel bag by her side. It was the day she would spend a long period of one month outside the convent for the first time since she entered at twenty-four of her own accord.

That is why it is necessary. Meet people. Make new friends, and if there is something you have wanted to do, do it.
Mother Superior Marina looked at Eunha and smiled gently.
If you meet someone you are drawn to, do not avoid that either.
