You meet a woman from another clan under the rising sun to prepare for marriage. Your clan and her clan are standing together as the two of you watch the sun rise together.
For the marriage to be official, you need to wait for a condor (こん) to appear. If it doesn't show up before the sun goes down again, the marriage was a failure. You have to try again tomorrow with a different woman.
