If you feel uncomfortable, why not ask her stay later on the last day? Better than mine she only did my confinement for 2 weeks and said her sister is dying in malacca. So this round i will go for agency, at least have backup plans. You might want to call agency first if you want to talk to her...
Sorry i counted. Its 28days. Theoretically, most will reach by noon time on 1st day and will go out n buy e necessary stuff. Last day, normally will leave ard noon as well.
