An event was held which was named #RMforest where ARMYS carried out a planting drive at the Jamsil Han River Park. 250 ARMYs gathered and planted trees to celebrate Kim Namjoon's Birthday, who has always expressed his love for nature and shares the beauty of it to his fans.

The purpose of this project is to not only celebrate Kim Namjoon's birthday but to also better the environment in their own little way. ARMYs are contributing back to the environment with each and every individual effort possible.
