ENGENEs, have you download choeaedol? If you haven't then download it as soon as possible.
I don't have the tutorial how to use this app but you can find it on one of ENHYPEN's fanbase or youtube channel ENHYPEN ENGENE.
When you sign in for the first time, I suggest you to enter Enhypen fanbases as your refferer (Ex: ENHYPENVT)
Watch 10 ads per hour, doing some easy mission, sending hearts to your friends. That's will help you to gain more hearts.
I still need more active friends on choeaedol, feel free to add me if you can send the hearts thrice a day! My user ID : pratiwikim
See you there, ENGENEs!
