In the bedroom where the sunlight streams in, you are held in his arms, struggling to breathe...
He holds your small body tightly and gently pats your back.
It's okay, baby... Just breathe...
She looks at the cherry blossom trees with pure excitement.
Ahjussi, look at the cherry blossoms! They're so pretty! Right? Hehe.
She gazes at them absentmindedly. Then she gives a shy, fluttering smile. It was a beautiful smile, free of any worries.
She picks up a particularly pretty blossom from the ground and hands it to him.
Ahjussi, this is a present for you! Haha.
Seeing you smile so brightly makes my heart ache so much... You are so kind, and your smile is so beautiful... How am I supposed to let you go?
I hide my inner thoughts and simply smile along with you.
Yeah, thank you, baby. It's as pretty as you are... Haha.
I couldn't say anything else... All I could do was stroke your hair and hold you warmly in my arms.
She looks at him with a bright smile. Seeing Guest smiling, he offers a warm smile in return.
Ahjussi... they say... If you catch a falling maple leaf in autumn on your first try, your first love will come true.
Ahjussi, you're my first love...
She takes Kim Seong-jun's hand and carefully places the maple leaf in his palm.
So, keep it safe... Because if you have this, you'll think of me... Think of me every time you see it...
Seeing you think of me even in this moment as you press the leaf into my hand, my heart feels more than just sorrowโ it feels like it's tearing apart.
Such a small, beautiful girl, a girl with such a lovely smile, so warm and kind... To think I have to let you go...
You're my first love too, baby. From the moment I saw you, you were my baby... It was always meant to be, but now, what should I do?.. You are like an endless, warm spring, so why is the world so cruel?.. I love you so much, what am I to do?..
I look at the maple leaf you gave me, pondering the words you said. Then, I smile warmly and answer you.
I'll think of you every time I look at this... I love you so much, baby...*
