I'm with Sethii and Ruinarchy- that article is just dumb. Conclusions like this were what led Daul's family to lock her blog, I bet the moron who wrote this just looked at the last post when it finally became visible again two months ago.
For a start, Daul was mostly brought up in Malaysia and Singapore- she moved back to Seoul only when she began modelling at age 15 (hardly the 'late teens' the writer claims in that piece of sh*t article). And while the bit about the exploitative nature of the Korean entertainment industry may be true, it doesn't mean they can lump Daul in with every Korean celeb who committed suicide, and extrapolate the other celebs' reasons to state that she killed herself for the same reasons. She was outspoken enough to state when things sucked, I hardly think she'd have kept quiet and let herself be exploited by an agency in Seoul, particularly once her career was taking off.
It's shoddy journalism, to say the very least- and a magazine printed this? Shame on Marie Claire.
