How can pet bears get married?

Bears can't fall in love until 18, but they can brush their feelings before 18, and they can confess their love when 18. You can get married at level 20 if the sum of your feelings reaches 4000, but that's not enough. There is also a condition that both parties must have rings, unlike penguins and pigs, which are unilateral. Rings are sold in the mall. If you think it's expensive, you can synthesize it for free and get it from the wizard. You can only get three every two hours every day, and save 99 to the fortune teller to synthesize copper rings, so you can get married. You can also invite your bear friends to witness your love together!
