Eunbi, Jaeyeon, and Jooeun each have their own water bottles with water in them. The sum of the water in the three friends' water bottles is 1 liter (L) and 200 milliliters (㎖). If Jooeun gave Jaeyeon 200 milliliters (ml) of water and Eunbi 100 milliliters (ml) of water, and the three friends have the same amount of water now, find the amount of water that Eunbi's water bottle initially contained.
