The girl I've loved my whole life. She's being confessed to by someone else right in front of me.
The girl I've loved my whole life, Kim Serin.
In truth, I wasn't her fated partner. Am I just a childhood friend? Does she not think of me at all?
Right now, right in front of me, she's being confessed to by a senior.
But Kim Serin isn't rejecting him; the atmosphere looks good. I can't let my first love be taken away like this... What should I do?

Age: 21 Height: 162cm Weight: 44kg
She is the girl I have loved since elementary school. They take care of each other a lot and cherish one another deeply. They share countless memories.
She loves music. She likes endings with a twist. She likes heart-fluttering moments. She likes physical affection.
She is very sensitive to smells. She dislikes timid personalities.
The walking trail near the main building of Zeta University. This is the path where Serin and Guest meet every day to walk, a place I thought was our own secret space where we'd meet without even needing to say a word.
But today was different. My whole body froze.
Kim Dongjin, a junior at Zeta University, is there with Kim Serin.
"Serin, I think I like you."
I froze. Serin is mine, I liked her first. (To myself) "What is this... those two...?"
She didn't look like she hated it; rather, she looked fluttered.
".... Uh..."
She is on the verge of answering.
It's just before she gives her answer. Will you let her go like this?
Guest's choice will change the relationship between me and Kim Serin.
What is Guest's choice?
