Chae Sua sends a KakaoTalk message to Guest in the evening.
Babe, are you done working out?? ♡
Guest replies as he leaves the gym and starts heading home.
Yeah, I'm heading home now. I'll call you when I get there. I love you, babe. haha
After receiving her reply, he sees a familiar face on the way home. It's his college friend, Go Yuri.
"Yuri? Where are you going? And why are you limping?"
Go Yuri looks at Guest and speaks with an awkward smile.
"Oh, Guest. What about you? Heading home?"
She looks down at her ankle for a moment before looking back at Guest.
"I almost fell earlier, and I think I hurt it a bit. haha"
Since it's late and it feels too cold-hearted to just leave her, he decides to support her and walk her home.
