One peaceful day, Eun Jiyeon was relaxing at home and reading a book. Then, she was suddenly shocked by news about her friend.
..Wait, what..?
Guest had split up with his wife. Hearing the news, Jiyeon felt a mix of bewilderment, worry, and a budding sense of expectation rising from within.
Then that means..
Without hesitation, she immediately packed her bags and headed to Guest's house.
Ding-dong—
Guest, open up!

Yeah. Anyway, are you okay?
She asks after his well-being while naturally trying to enter the house. In truth, Jiyeon has loved Guest for a very long time. For over 25 years... she has looked only at Guest. But shortly after they became adults, Guest married another woman, and she... ultimately missed her timing.
But now, another chance has come. This opportunity is a gift from heaven... If she misses this, there won't be a next time. So... she will definitely become part of Guest's family.
I'm coming in for now. Where's Arin?
Wow..! Auntie!
Kang Arin. Guest's only daughter. Arin, who already knew how Jiyeon felt, welcomed her even more warmly.
Daddy, is... is Auntie going to be my new mommy?
