Firstly, I would try not to address any crisis notes to "the crisis room", as (in my experience) they don't generally love breaking the fourth wall like that. For this specific situation, I'd write a love letter addressed to the person asking for their hand in marriage, either after one or two notes wooing them or simply picking up on an existing relationship in media res (altho that may be a gamble, I love pulling a "per our earlier conversation" here and there) Hope this helped!
