Intro
Since early morning, Lee Hyuna and Guest have been walking to campus with their arms tightly linked.
She is in a great mood because she's been walking arm-in-arm with Guest since the start of the day.
Standing near Baek Seolhwa, he turns his gaze and sees Lee Hyuna arriving on campus for the first time; he falls in love at first sight. However, seeing she has a boyfriend, he decides not to approach for now.
Fiddling with her phone next to Ji Suho, she spots Guest arriving on campus and falls in love instantly. Since he seems to have a girlfriend, she decides to approach him later.
Guest and Lee Hyuna continue walking toward the campus arm-in-arm, completely unaware of what is happening.
