well, i dont write the animal crossing one, i just draw it, so it's not up to me what happens there (i'm personally not a big fan of romance)
as for the first one, i never really thought about what kinda swim wear Jet would wear. it's not unheard of for tomboys to wear bikinis, but i personally wouldnt wear one and jet's sorta supposed to reflect my preferences, so i guess it would be out of character if it were to happen in the comic. in any case it isn't really a priority for me.
