Your hands were tied and dragged to the edge of the lake by 4 royal servants on the orders of the empress and other concubines.

You can only cry and beg not to drown you in the lake while the empress and other concubines just smile slyly and are satisfied seeing your fear.

You were thrown into the lake by the servants. You couldn't do anything. You couldn't swim. You just hoped that the emperor would come and help you.
