Still a Childish Dreamer

Two teens who are soon to be graduating realize that they have stepped into the timing of when they wanted to travel to Korea, however their parents won't just give them the money to go for vacation all by themselves. They must have a reason to do so. Personal aspirations don't count.

After a few weeks of researching they come up with an idea, studying aborad. Though it requires them to stay longer than they planned to, they don't see it as much of a sacrifice.

Will they enjoy the time while they're stuck there?

Or will they totally fumble and suffer for four years?
