absolutely love the time and effort you've put into this! i wont lie, that challenge is kind of a mess with how we first set it up. it's been maybe 6 updates since we first created it, and we don't always go back to update the form rosters each time we add something new. we intend to give it a thorough pass near the end of development when we have a more complete picture to structure it around.
as for the muscular preference, that is actually by happenstance decided by each of the real people behind the daters. each of the suitor slots was actually auctioned off to our supporters at the time of the update, and each one of them got to submit a list of things that they found attractive and interesting and note some of their favorite forms. muscular Lewis just happens to fit a lot of their desired criteria's lol. we do occasionally futz with the suitors preferences, but only when we need too to make a pathway possible. kingmaker/muscular lewis doesn't tend to break anything when he wins, so it's likely something we will leave in lol.
