Fym messed up our order, is this mf pram gay?
Ah, you must be new to the manga/manwha type series.
While that could be a possibility, no less than 90% of the time characters like pram are girls who for various reasons insist on hiding their true gender and acting as if they are a boy.(many commonly refer to them as reverse traps) In this story, pram is probably doing so for greater appeal in the search for "his" noble father.
A son who is well accomplished is more likely to be noticed than a daughter.
Given the artistic context clues and how pram acts, as well as other characters(cough romantica) reaction to pram, as well as the general vibe of the story, I am pretty confident pram is a girl. (Even that green knight guy thought pram was a girl at first, accepted pram as a boy, and then wondered if pram really was a real boy and not a girl pretending)
I wouldn't say though that even if pram is really a boy, pram doesn't necessarily need to be gay persay(romantic orientation). It is possible he just wants attention of MC in a sibling sort of way(which mc treats as a young brother often), and thought he could be useful for once being able to teach MC a skill.(how to dance).
But again, pram is 90% or higher a girl, and this party is either a harem or quasi harem.
