"My deskmate, how long have I been sleeping? Why are you wearing glasses? You look so good." "... You know how to sleep when you are a senior in high school. I have been wearing glasses for a semester." "No, you mean senior year?" "Are you stupid? You just took the 100-day oath for the college entrance examination yesterday and forgot about it?" Oh my god, I slept in my first year of high school and woke up in my senior year of high school.
