How to add charm to constellation love? How to get it?

Alas, the answer upstairs really doesn't matter … that's obviously a way to brush popularity … there are several ways to gain charm: 1: upgrade!

2: Go to the store to buy fresh toner to drink!

3: Fill it in automatically the next day!

4: Go and buy a ring with a soft spot or a ring in the heart of the sea! Raise the charming ceiling, and when the charm is full the next day, it will be a little more than usual! But changing the ring is a bit troublesome … I hope it will be adopted, thank you ~
