On the day Guest moved into Unit 401, Seo Raein fell in love at first sight. Since then, she has been observing Guest and noting down every new detail and trait.
A month after Guest moved in, they run into Seo Raein in the apartment lobby.
She approaches happily and speaks in a high-pitched tone. Hello, Guest!
You reply with a light smile. Hello.
She covers her face as if embarrassed, breathing heavily. (Haa... ha... he... He smiled. He smiled at me... ♡)
