It's not about legality, but possible abuse of power. A 30 year old adult can make a 21 year old financially dependable and they CAN abuse someone younger and less mature than them, who now can't escape because of monetary needs.
THAT BEING SAID. This is not the case.
It's been mentioned that Yuri's family is wealthy and he got a part time job just to get familiar with a working environment, not because he needed the money. If we talk solely about money, Yuri could even be at an advantage.
And regarding their mental state, they're both in the fucking gutter and need therapy. Yuri is at "an advantage" if you don't look close enough, but Seonwoo could just run away if he gets tired enough, so they're equals.
All in all, their age gap doesn't matter. They re-met as adults, never had anything remotely close to a romantic relationship when they were teacher and student. It doesn't matter, the drawing was just made to make people see them in their past, which looks cute tbh. Stop bitching around.

They'll change like two more times aside from this second one, so if you don't like it, these are bad news ╮( ̄▽ ̄)╭
The changes will eventually make them know each other more and grow as people so don't worry, there's a lot of development. Of course it'll also lead to hilarious situations for both of them.
I'm sorry but, why are people whining so much about the long strip format? It's still easy to understand, it's not congested, and the new scanlator kindly picked it up FROM SCRATCH because some pages were missing and it was confusing. It's not the biggest change, you'll adapt in a chapter or two, and you're also missing a ton of great manhwa if something so small bothers you.
Be grateful, this is all for free.
