My Tutor Friend 2 (2007)

Su Wan is a sophomore in college, and she works part-time as a tutor to cover her tuition since her father lost his job and started a small chicken eatery. It's been only 7 days since she started teaching her new student, and already she's been sacked. "No tutoring, no tuition," declares her mother to make sure she understands she has no choice. So Su Wan is back on the market and meets her next challenge - the impossible, the unconquerable and the unreformable Ji Hoon.
Su Wan is determined not to lose this job since she doesn't want to disappoint her Mom. And from then on, things start happening one after another.

it's the part two but totally different story. my tutor friend is about a wealthy young man who should not finish High school and his family hire a tutor for him. While my tutor friend 2 is about a exchange student and a girl who go to seoul hoping to see korean student who she had fall in love, and also hire a tutor for her studies...

In Rainbow rose the FL's family runs the boarding house with ML being the exchange student from Japan , in My Tutor Friend 2, the ML's family runs the boarding house and the FL is a student from Japan
