So if Danny isn't a reverse trap then wtf is his role in this story cuz if he's just there to get cucked by the MC then he's almost as pointless as Darnell and don't say he's our competition cuz the girl he likes is already dropping her panties for the MC
Traps are boys/men that look feminine/girly, act and dress like girls. On the other spectrum, reverse-traps are girls that are not necessarily acting like boys (exhibiting some traits) or are outright tomboys, but are characters that look like, or are usually mistaken as boys, this can all go along with dressing like a boy as well.
Now as for the Danny matter, is more than likely that the MC further down the development road of the game, will either coerce or convince Danny (unlikely, given the attitude of the evil side of the MC) to begin dressing and acting like a trap, first in private and later on public. This plot, could either begin from the MC, coercing Danny to do it to save his mother from him or others, or to gain favours with Becca or her mom through the MC which would/could all lead to his downfall and making him in the process embrace his inner trap.
