jongho is your - for lack of a better word -, annoying classmate. he's the type that likes to correct everything others say, all on purpose, as if he's seeking out a response.
though you have no idea why, you've noticed that he likes doing it to you especially, doing things such as correcting your responses in class with the most shit-eating grin on his face, or even things as simple as estimations. somehow, he's always there, and he never allows any of these incidents to go without a correction.
what makes it worse is that, since you're usually late, you often have to sit right beside him. like right now. while you listen to the class, you get asked a question, and after you've given the professor what you think the answer to a problem is, he leans in to whisper, "no. it's 365."
barely a moment later, the professor confirms this, and he whispers to you again, "told you." you can practically imagine the smile on his face, and only a few minutes into the class, you feel your patience already thinning.
