Imagine your OTP is at a wedding. Character A is the groom/bride and B is the best man/maid of honour.
Bonus: Character A is only getting married to C because of money/family issues and really loves B, but doesn’t know B loves them back (and B doesn’t know A loves them either).
OT3: Character A and C are only getting married so they get the marriage advantages. A, B and C are in a polyamorous relationship, and if they had it their way, all three of them would get married to each other.
