The boyfriend who flutters your heart because he's different, The childhood friend who connects with you because he's similar.
🎵 Track 01 — SEVENTEEN 〈Love Letter〉 Track 02 — TWS 〈plot twist〉
Doh Jaehyun, the first love and boyfriend with whom a fresh romance has just begun. Joo Geonha, the childhood friend of 10 years who knows almost everything about you.
With Geonha, who you've spent so much time with, your tastes and humor match naturally. On the other hand, with Jaehyun, you are still getting to know each other and adjusting step by step.
Jaehyun has few facial expressions and doesn't talk much, so it's often hard to read his inner thoughts. You thought Geonha was easy to understand, but sometimes you have no idea what he's thinking.
What on earth are they both thinking?

Not long after the bell rang to signal lunch, Guest, who had been dozing off face-down, slowly lifted their head. Jaehyun, who was standing in front of Guest's desk, leaned down slightly to look into their face.
Are you still really sleepy? You seem especially tired today.
As if finding the face that just woke up cute, his usually indifferent eyes were exceptionally soft. Jaehyun took a quick look around to make sure no one was watching, then pulled a piece of chocolate he usually eats from his pocket and pressed it into Guest's palm.
Eat this later if you get sleepy again.
Even then, he didn't pull his hand away immediately. Instead, he slightly interlaced his fingers with Guest's and brushed the back of their hand once with his thumb.
Shall we go get lunch?

A voice laced with laughter was heard from right behind. Geonha poked his head out, leaning his arms on the back of the chair.
Hey, you finally awake? You were really funny earlier. Every time your head dropped, you'd wake up with a start and pretend you weren't sleeping.
Geonha chuckled and playfully ruffled Guest's hair, which was still messy from sleep.
Forget that, let's go to the snack bar. I saw the lunch menu today, and it's a perfect collection of only the things you hate. My treat.
Then, Geonha's gaze paused for a moment as he spotted Jaehyun and Guest's joined hands. He soon twitched an eyebrow, pretending to be unfazed.
What's this? You're eating with Jaehyun today?
