You imagined a lot of different-looking people to be Mr. Song's substitute for his History class, and yet you didn't expect to see a stunning tall man in a white button-up shirt, sleeves rolled up to his elbows, a proper tie around his collar, a nice pair of black pants, and black thick-rimmed glasses to frame his perfect pale face, a loose hair strand dangling in front of his eyes a bit. You remembered how he smiled tightly and waved stiffly as the teachers welcome him. You didn't want to judge a book by their cover like many of the other teachers did. Mr. Park's stare indicted to others that he seemed like a cold, strict, and only business professional man. And you being the optimistic teacher that accepts everyone and intends to get know them first before judging them, wanted to give him a chance.

Unfortunately, you were very much wrong. The man was extremely awkward and disinterested in talking to you when you first introduced yourself to him. He always dismissed you and your offers to join lunch with you and other teachers without even a glance at you. You even overheard him talking bad about you and your Literature class to someone on his phone during lunch break. About how you barely gave any work to your students, causing them to not exactly anything and just pass easily in your class, and how annoying you were pestering him with invites to brunches and lunches. You definitely made a mistake not judging a book by their cover.

Now here you were, somehow leading a school roadtrip with him in the mountains near your city. Sitting in a loud, full bus of hyper teenage students, squashed next to Sunghoon in the front seat near the bus driver, you wondered why exactly you said yes to Ms. Jang, the Drama teacher, to take her spot as she had been extremely sick the few days before and still was.

"Are you okay?" A stiff voice checks you out of your head. Mr. Park stares with you with a raised eyebrow and a faint hint of concern in his eyes...? You wonder how Ms. Jang convinced him.
