First, there will come a time when BoA retires...
But I get what you're saying (that now is too soon).
When Koreans say she's "not trying," it refers largely to the lack of special stages/performances she does. Even when she did "Only One," a very strenuous song with a very difficult dance, Koreans were consistently underwhelmed because it was almost always the same performance. She does the standard routine and rarely changes it up. In comparison, you see almost every one else in the Korean market doing remixes, new dances/dance breaks, covers, etc. They add something so that their performances aren't the same all the time. Yes, this leads to some bad performances (because they have a short amount of time to practice), but it shows the audience that they're trying and makes things more exciting. Nowadays, BoA RARELY ever offers anything new to the typical routines she does, so the impression that Korean audiences get is that she's "not trying" to add anything special.
I have no doubt she's very sad about the poor performance of the album, which is merely a snapshot of what she's been experiencing these past few years. I'm sure she was sad about Make Your Move consistently being pushed back and the poor turnout at theaters (especially in Korea -- where it really hits home, both figuratively and literally). I'm not sure if she even cares about her Japanese career, but there's that as well.
These next few months will be important for her to decide what she wants to do with her life (she's still young!) and how "resilient" she is in terms of bouncing back from failure (and in her case, multiple failures). It's particularly challenging for her because she tasted HUGE success at such a young age and to see her former popularity dwindle down potentially hurts more than someone who's never had success at all.
I would suggest she look at options outside of Korea. She's in a market that doesn't bode well for older female soloists. If she were in the American market, for instance, no one would be calling her "old," and retirement would be in the distant future. KML would also have better public reception. However, it seems that these days, BoA wants to focus on her Korean career. :|
