Masks and Grades [Daehyun x Jongup]

Daehyun was a smart guy but his attitude wasn't nice or friendly, and he always had a mask covering the lower half of his face. Jongup was a guy who kept on smiling no matter what the situation is and would always try hard but always ended up with bad results because of his nervousness and lack of confidence.

Daehyun took off his mask and placed it on Jongup's face because he didn't like seeing the guy smiling in a supposedly sad situation. Since then, they influenced each other to improve.
