Sincerely, Addison [XO, Kitty]
12 parts Complete Addison loves all things Korean, and when she gets a chance to go to an international high school in Seoul her senior year, she pounces on it. When she gets there, she's immediately met with a problem... she falls in love with a Korea-born Australian guy who she thought was a student at first but turns out to be one of her teachers. How will she concentrate and pass his class? She has to get a tutor for the class so she can pass it, but that tutor, who is a native Korean, falls for her, as does his roommate. Matters get worse when she suspects that her teacher has feelings for her, too. It could get her expelled and him fired, especially since student-teacher relationships are forbidden.
Sequel to the Netflix series "XO, Kitty" and with the same characters, just a year later. Season 2 hasn't come out yet, so I just made up the continuing storyline.
