Thanks to 1arigato for pointing out that e.g. if a character likes something from option 1, the other answers for him/her would be option 1 too, and chanchan for pointing out that there are 4 groups of answers. This allowed me to draw the parallel that each group correlates with the characters’ elements. With the amount of sample size/confirmed answers we already have, it’s pretty much certain (thanks so much everyone for all the inputs!!), so here’s a table for easier reference.
