Remove couple propose cooldown

Hello,

I'm new to the flyff dev world and I wanted to start learning from the simplest code.

Changing or removing the couple propose cooldown..

For the love of me.. I cannot find in the codes where does it set the couple propose cooldown nor where does it store it..

I tried searching for the database to get an idea but all for naught.

The source version that I'm using is v15 since I cannot find a v18 source that both does not have a backdoor nor can i compile properly.

In anyhow could someone enlighten me on this one?

Thanks and have a nice day. :)
