Character weddings are now available on the english versions. Just go to Holy Village and then talk to the NPC Nun (or Priest, as titled) (X: 3302 Y: 1095) that is in front of the church behind a stall. You can also get a divorce if you are already married. After you've talked to the Priest -or Nun-, she will ask you to head to the Holly Village pool; the center of Holly Village (X: 1642 Y:1275). You will stand in front of the pool, and the cupid statue will have shot you with a Love Arrow. You now have a Love Arrow in your inventory.
